Hey, it's an interesting idea to use Artisan of Forms, but I think it might be kind of redundant since you need to have another one of your Heroic creatures out to get Artisan of Forms to become it (unless your opponent's playing is playing Heroic as well), so it would normally be more beneficial to play your Karametra's Favor on the other heroic creature instead of Artisan of Forms.

Positives: You could enchant Artisan of Forms with Karametra's Favor early when you don't have your other heroic creatures out and have it switch into any of them once you get them. Grim Return, Deadbridge Chant and Immortal Servitude are cool choices, since you can get your creatures back if they're killed or countered.

Negatives: Artisan of Forms turning into another creature doesn't really do anything to help you win the game like the other Heroic creatures (deal damage, mill, etc). Also Artisan of Forms' ability doesn't trigger Heroic (because only cast spells targeting the creature trigger heroic, and abilities do not), so there's not much of a benefit. Replacing a couple of them with some more of those other creatures will speed the deck up a bit. You may also want a few tutors to help you fetch what you need. You have some draw which is great, but I think cards like Unexpected Results are more likely to fail you. You might get an Elite Arcanist without an instant in your hand, and that may be a waste.

Sure, it seems like an interesting idea to use Artisan of Forms.

Thanks for the suggestions. I'm going to test it out to see whether the Bident will work better.

Thanks for the suggestion! I'll have to test out whether or not the Bident will work better, since it really depends on whether I can deal combat damage for the card draw.

Hm... I've never thought of Nykthos as a mana fix, more of a mana accelerator. If I had only islands and swamps, and I needed green mana, Nykthos wouldn't be able to give me green (since I'd probably have no devotion to green). I like Nykthos in mono-colored/devotion decks because you tend to get a ton of mana, but here I think a Nykthos would get you maybe 3-4 black or blue mana, but since you have to tap 2, you're really only getting 1-2 more mana. So by that logic I don't think it's worth it to put a Nykthos in here.

Looks like a pretty solid deck!

I like the amount of card draw you have here, and the fact that this version of the deck is on a better budget. Suggestions I can think of are maybe adding a couple of Diabolic Tutors to help you get the combo, or maybe a couple of Horizon Chimera to take advantage of how many cards you're drawing. Other than that, nice work!

Thanks for the suggestion! Simic Charm is definitely going in.

Thanks for your critiques guys. It's true that the deck is reliant on the Elite Arcanist, mostly because that's the only recurring trigger for tapping and untapping (which is what I wanted to base the deck on). I'll look into some more options for recovery though. Thanks again.

Thanks! Good suggestions, I've added Urban Evolution and Voyage's End to the deck and removed Kiora's Follower and Prophet of Kruphix.

I've also replaced Negate with Swan Song since it's been suggested twice, but I'm not quite sure I like giving them the 2/2 flier that I can't really deal with just for one less mana.

Thanks, I was thinking of Burst of Strength while I was making the deck but I found that I don't really have a way of maximizing the +1/+1 counters. I could exile it with Elite Arcanist for more uses but I found it too slow, and I'd rather save the Arcanist for Triton Tactics.

In my other version of this deck I included Vorel of the Hull Clade to double counters from Burst of Strength, but ended up using Forced Adaptation instead because it produces more counters for Vorel to double, even if it doesn't untap a creature or work with Elite Arcanist.
Here is that deck: http://www.mtgvault.com/phlight/decks/karametras-infinite-favors/

Thanks for your suggestions! The Hammer is a really good idea, and Swan Song's an interesting choice for an alternate counter. Sylvan Caryatid and Springleaf Drum hopefully helps with double costed cards, so it shouldn't be too bad. I don't really know what to take out for the Hammer though, any ideas?

Thanks! Even though it's not super competitive, I hope that it's at least fun to play.

Thanks! I was actually looking into Inspired as the core mechanic of this deck, but found that a lot of them require you to pay mana to activate so you would not be able to chain the combo very long. Others that I left because they didn't really become a win condition like the creatures that gave themselves +1/+1 without evasion of some sort, giving creatures -3/-0 for the turn or giving creatures intimidate.

Inspired cards that I do like for this are: Siren of the Silent Song, Oreskos Sun Guide and Servant of Tymaret which are in the other iterations of this deck:

Thanks for the comment, I know this isn't super competitive but I thought it was interesting because of the options it presented and just wanted to play around with it.

Kiora's Follower definitely doesn't help the infinite combos, but is there just to help trigger some tapping/untapping early on in the game if you're ever stuck without Elite Arcanist. At worst it's a 2-drop that allows you untap a land like Voyaging Satyr except you get to choose Zhur-Taa Druid or Sylvan Caryatid as well.

Thanks you for the comment. I didn't intend drawing yourself out as the mechanic there, rather that you can basically look for any cards that you need to win. You would just need to dig up another Karametra's Favor and a game winner (and maybe just a Negate or another Elite Arcanist and Triton Tactics just to be safe). I've changed the description to reflect that.

You're also right about Jace crippling the Crusader plan. I'll also fit Springleaf Drum in here somewhere. Thanks for the suggestions!

Thanks for the comment, and sure thing!

With Cauldron Haze (and other spells that allow you to target any number of creatures), you can only trigger Heroic once on each creature you target. It doesn't allow you to target a creature multiple times.

Hm, I'm not sure whether the kind of mana fetching in this deck is fast enough to cheat out Wordspine Wurm. The tokens are pretty cool, but I think the Worldspine Wurm would work better if I threw some Populate in this deck to duplicate the tokens. Thanks for the suggestion though, it actually got me thinking whether or not to replace Experiment One with Elvish Mystic for quicker mana-acceleration.

Well, I had Kragma Warcaller in but I took it out for the Hammers because they were just cheaper for haste and I thought that trimming it down to 2 colors would be more consistent (but I didn't change the mana base). Thanks for catching that. I've added the Warcallers back in though just because the +2 buff is pretty good. Plus I can only have 1 hammer out since they're legendary so I've gotten rid of one.
