The only thing I would change around now is your mana. You have WAY more white cards in the deck, rather than multi-coloured. I would put in more seaside chapels, sunpetal groves, and glacial fortresses, that way you can have the white mana, but also still have your multi-mana too. Other than that, if you don't want to increase special lands, I would drop a forest and an island, and put in two plains.
Deck is looking good.

That's not all. If I can't get the Hellkite out, I can always blow up the field with Vandal Blast.

I've noticed that you usually make all your decks around 65 cards. Nothing wrong with that, but have you ever had trouble getting what you needed when you really needed it?

I love this deck. I like having people find ways around Eldrazi costs. The only thing I can even think to recommend is Cloudpost and Glimmerpost. They send your mana skyrocketing out of control if you get a few of them out.
Excellent work.

Since I'm guessing this deck is for casual play anyway, I would suggest you remove 1 off of each thing you have four of. Usually, you wouldn't need four of some something unless it is insanely broken. Might I also suggest getting some Memnites or Ornithopters so that they can blend well with your master transmuters and be easy drops to use as defenders for the early game.
I have a few artifact decks myself, if you'd like to check them out, I'd appreciate it.

This is a fun idea, but the deck looks like it'll run a little slow. Try adding in Dark Rituals or Crypt Ghasts to try and speed things up a bit. Also, Spiteful Visions is a fun card to burn your opponents with, and it makes sure that they have cards to be discarded for later. Sign in Blood would also be a fun card for this deck.

If I were you, I'd lose Akroma, Avacyn and cut down many of your doubles. Increase your low drop exalted and focus on making them unblockable, rather than having them get protection for two colours your opponents might be playing. The faster your exalted can build, the faster your opponent dies.
Things such as Spirit Mantle are a must for this deck, or you could even add in a few Invisible Stalkers. They might not be exalted, but damn it, they are hard to get rid of.
Also, look into Silent Arbiter, rather than Stoic Angel. He makes exalted so much easier!

Yeah. I could see that being an issue. Have you considered plummet or burn spells to deal with flyers or annoying creatures or just direct damage boosts?

Not a fan of pit fight to be honest with you. Daybreak ranger would basically just do that once she transforms.

Thank you for the idea. I'll be sure to check out your deck as soon as I'm done with my newest project. If you have any other suggestions, please tell me.

Since I'm not remotely custom to the power and creature amounts that green and red come with, I could use some help making this deck more effective. If you have any ideas or suggestions for the deck, please let me know. Thank you.

Really, I have that card in there so that I take less damage over time. It's pretty annoying to have to deal with creatures that just poke me to death. I could sideboard it and throw in more stalked prey and pierced heart.

I see your point. Now that I think about it, I can't actually remember why I put righteousness in the deck in the first place. I think it was mainly for a place holder until I think of something better to add to the deck, but looks like I don't have to think of anything better. Others have done it for me.
Thank you for your help. If you think of anything else that'll run smoothly in the deck, please say so. I'm always curious to hear other's opinions.

Ah. Alright. I've put in the Metamorphs. Thank you for the help. If you see anything else that could use any changes, don't hesitate to say so.

I know it's not the fastest deck around, but in a casual fight, I've noticed that people are a bit more passive and don't immediately gun for someone until they see what the deck can do. I figure that since I can't use this in tournaments, I'll just kick my friends asses with it.

Thank you for advice, it was mostly so I could do more damage and keep them from using their graveyard to hurt me, but that's really circumstantial so it's been sideboarded. If you see anything else that may need to be put in or taken out, please let me know.

I just wanted to say that this deck was the biggest inspiration for when I made my artifact deck. With my play group, if anyone noticed that I played a Cloudpost or Glimmer post, I would instantly become the main target of the game and would be killed off around... turn 4-5 if I could throw Platinum Angel out. After that, if they couldn't take care of Platinum Angel they would scoop and I guess I won every time I played with it. I have to say, I took a lot of the ideas that are in Twisted Around and kinda turned them Upside Down.

Thank you for helping me create a deck that my friends hate so much.

If the deck is supposed to be a support deck, then I would keep it as it is. Unless you actually want to take this thing into a fight, by yourself, and win. You could try and get Griselbrand or a few Divinity Of Pride. OH! Or that Vampire. Blood Baron of Vizkopa or Vish Kal, Blood Arbitor. Decent enough creatures with abilities that could win the game for you.

Thank you. I put in three to just add more respect to the name I've given the deck. I actually didn't notice that I had a lot of 3's in the deck. When I came up with the title, I was just thinking that nothing in the deck costs more than 3 mana. Is there anything else you could see in the deck that I should take out/put in?

Honestly, I love Phyrexian Metamorph, but I have no idea what I should take out in order to sub him in for. Any ideas?
