You know it's funny. Totally worth it.

........Eh. Idk about a deck that simply doesn't want to die is all. Very intresting concept. Could be worse. You could literally have made the deck 20ish swamps, 40ish Relentless Rats. *shrugs*

I don't feel the Angel's Feathers are necessary, but I'm also not going to tell you you can't run your combo. It looks fun, kindof a backup there. If you decide that you're going to go one way or the other w/ your deck, I recommend taking a look at ryan1028's lifegain deck. It's retarded in a multi. He regularly gets over 100, no problem.

Like I said, looks fun though. I'd Banefire you for what I'd presume to be lethal. And then see the Grace drop.

Probably sit around for awhile afterwards, trying to figure out how I lost. Probably Banefire you again for being a jerk or something. Because it's funny.

I recommend you take out Carnifex Demon. You'll wipe your field too in the process, and if the idea is to infect and kill w/ proliferation, he's probably going to hurt you moreso than help you. Instead, slap a playset of Plague Stinger in there, take out Skinrender, get Phyrexian Crusaders and Hand of the Praetors, Inkmoth Nexus if you like that one.

...Maindeck Crusaders I should say, not sideboard them. Skithy too. Might as well at this point. Those Trigons you can probably do w/o, especially since they're one ofs in here. Inexorable Tide is great, put 1 or 2 more in if you like that, playset Steady Progress and take out Instill Infection. If you want to do some neg ones, put stuff like Virulent Wound in. 1 mana, -1 a creature, if it dies this turn, give someone a poison counter.

Hope that helps. It's green/black, but ryan1028's infect deck is amazingly brutal and ungodly fast, consistently. You might get some ideas from it, you may not:

Unfortunately, because Magosi reads that you have to pick it up, the counters go away, so it's not a terribly effective way to get a billion turns. It sucks, but that's how the card reads. :(

I didn't mean to cause offense, I was just backing that, based on the currently available type 2 cards, black/green is the most viciously lethal and efficient killing machine for infect. If you're running this casually, then please, disregard my arguments about speed. Run it however you like, I've nothing to offer other than instead of Soul Stair, you may consider Disentomb or Grim Discovery for picking creatures back up. In fact, I would probably back Grim Discovery moreso because it lets you grab a creature AND a land (Inkmoth).

Crusader lets you get past red and white decks and they can't stop it. At all. If that fails, you have a 2/2 first striker, and once they see that you're buffing it if they don't block, they'll block it at all costs. I feel 4 is necessary, but you can get by w/ 3 probably if you don't like it as much as having 1 more of another card.

Running green/black allows you to get mana as early as possible and have the power to swing for early kills. You don't want your opponent blocking everything you throw at them. Having Inkmoth as the sole flyer in a mono green infect deck means you're stuck on the ground hoping to get through. Plague Stinger allows you to fly over them, like Inkmoth, but you pay for him once. You never need to reanimate him for later swings. Running mono black doesn't let you get mana drops as early as possible. You have all the power, control, and flying in the world, but you don't accelerate your mana at all. You're stuck playing at the same speed as your opponent, and you don't want that. Green/black allows you to start hitting hard turn 3 if you don't get Garruk, and honestly, the deck can win just fine w/o him ever hitting the field. BoPs and Llanowar Elves make up the difference in mana accel. Did you even look at ryan1028's deck that I linked?

I recommend running it green/black. Infect is most efficient when you're swinging for lethal consistently on turns 4-6, 7 or 8 if the opponent is able to stop your creatures early. You don't want to drag the game out at all. Kill them early before they have a chance to build up anything significant. I recommend ryan1028's infect deck as a reference:

You won't find anything faster that runs consistently. I saw a turn 2 or 3 kill, and while it works, it requires the perfect hand to do that. It's not terribly effective otherwise.

The entire point of infect is to deal direct damage to your opponents as quickly as possible. What do you need to do that? Mana. And how do you do it quickly? Accelerate it. Birds of Paradise, Llanowar Elves. Turn 1 drops, gives you 3 possible mana turn 2 for a Plague Stinger and another BoP or Llanowar, turn 3 Garruk untap 2 lands play whatever you feel like (another Stinger, Phyrexian Crusader, something), swing w/ the first Stinger, turn 4 Putrefax or really whatever (you won't need it, but it's overkill), Overrun by saccing Garruk, swing. Even when you don't draw Garruk, you don't absolutely need him. Giant Growth and Vines of Vastwood do the job. Swing w/ Stinger and Inkmoth, buff them. Most infect damage that goes through is dealt in the air, because not too many type 2 decks these days are full of flyers.

This guy knows what he's talking about, trust me. It didn't even register on me that there weren't any Hands in here. That's crazy. He's as necessary as Garruk and BoPs.

The sideboard is cards that are sort of situational for the deck. In a tournament setting, the sideboard is EXACTLY 15 cards that you may choose to switch out on a 1 to 1 basis after the first match out of 3 w/ an opponent. In casual, I highly doubt anyone's going to care what your sideboard size is or when you choose to sideboard, provided you don't do that during the middle of a game. Nor will anyone care if the size of your deck changes because you simply put those cards in. Example (tournament or not): You've got 2 Go for the Throat and 2 Doom Blades in your main deck. You go up against another black deck. You know off the bat when you see a couple vampires and some skeletons drop that your blades are worthless. Game 2, you take out the 2 blades for 2 throats and make any other adjustments you wanted, and then you play again.

Use what you got man. Order/trade/buy what you can afford. That's Magic for you dude. Big money hole. But damn it's fun. Even though a deck may run the same nearly every time, there's such a wide variety of stuff out there than the games never seem to be exactly the same, especially in a multi. One guy might get mana screwed, anotehr creature screwed, others are running pretty standard for their decks, and spells just start flying.

Rupture Spires too. Looks fun. Good job. :D

Yeah, I thought about Jace's Erasure. I might at some point, or sideboard it, because I play a fair number of people that violently hate mill as a win condition, and Jace's Erasure in this says that my opponents don't have a deck anymore. I don't like mill either really, but it's an effective tactic. It works, and there just isn't alot that protects from it. Eldrazi gods, Elixir of Immortality, Feldon Cane, Quest for Ancient Secrets. I know it's a pretty big deck, but this isn't made to be competetive. It's fun for me, and there's enough fun stuff in here that it's great in casual. Albrek made a very trimmed down version of this, and while I'm sure it works, it's not quite what I wanted to do w/ the deck, though I figure it runs fairly smoothly. Search Jace/Liliana synergy v2 or something like that, it should show up.

Well, you can run stuff like Disperse or Into the Roil, which bounce a nonland permanent. 2 mana each, Roil has a kicker that lets you draw a card if you so choose to pay it is the only difference. And Disperse is reprinted in Scars. Meh. That doesn't seem like it matters in this deck though. If you really want more Cancels, Stoic Rebuttal is a type 2 Cancel, or a Counterspell is you have metalcraft.

If you draw into another Garruk, you simply Overrun as soon as it's reasonable to do so and play the 2nd the next time you've got the free mana to do it. If you have the spare, animate Inkmoth, cast Garruk again, untap Inkmoth and something else, swing like a boss. Garruk is incredible mana accel, and you can Overrun the turn after you play him for nothing mana wise. He makes an infect deck run so smoothly and quickly it's really not even funny. I'd drop the Hydras for Putrefax. Yes, he dies end of turn, but it's a 5/3 trample infect haste. Overrun w/ him, that's probably game. You can spare a Groundswell or 2. 8+ boost spells like that is plenty. Vines and Growth are your 2 better buff spells here for the most part, 2 more from Groundswell just means you'll likely have 1 every hand no matter way.

I don't see anything in here requiring Rupture Spires. Swap those out for islands if you want 24 mana, or Mana Leak/Spell Pierce. Looks like a fun deck otherwise.

Consistently though? That's the problem I see. How often do you hit that w/ this deck?

I'm suggesting BOTH BoPs and Llanowar, but that's just me. Color fixing and general green accel FTW.

Birds of Paradise. Mana problems fix'd. More Garruk too. Ramp that mana. Get some Engulfing Slagwurm. Delicious.

Not joking either. It works. Gives you more turn 1 options, possibility of Garruk turn 3. <3 Engulfing Slagwurm, obviously. If you need to protect your creatures, Vines of Vastwood is supershroud for 1 green, kick it for 1 green and it boosts creature +4/4.

Looks solid for blue/black infect, I just don't feel that blue/black runs nearly as quickly as green/black because green/black ramps mana w/ BoPs and Llanowar Elves from turn 1, Garruk being a possibility as early as turn 3 if he's drawn. Being able to kill your opponent from turn 4 on regularly, most decks can't handle that. I ran a deck by ryan1028 that I helped adjust and speed up in a local tournament, consistently killed opponents turns 5-7, once turn 4, and 8 or 9 when I played a mirror deck very similar to his:
