This is kind of more of a joke than anything else, but it could hypothetically get Emrakul, the Aeons Torn our on turn 4. The Vexing Sphinx is there for infinite card draw when combined with Gilder Bairn then draw and use Laboratory Maniac to win.

Just to give you guys some inspiration, the Gilder Bairn/Training Grounds/Paradise Mantle combo could give you other things as well: infinite +1/+1 counters on a Primordial Hydra, infinite charge counters on Darksteel Reactor or Umezawa's Jitte, a fully loaded Goblin Bomb with infinite fuse counters, Jace, the Mind Sculptor with infinite loyalty counters (or any other cool planeswalker), really anything cool that uses counters. Try some of these out if you want to.

Just playtested. Managed to win on turn 9, which seems decent for a joke deck like this. Took me while to assemble the combo, but got all the pieces on the field by turn 7. On turn 8 I started the combo, taking my Pentad Prism and Aether Vial into infinite. Used those to put the Progenitus and Emrakul, the Aeons Torn onto the battlefield. Turn 9 I swing with both and won (assuming the opponent had no colorless creatures to block Emrakul. Theres nothing they can do about Progenitus). Technically I won on turn 8, from Emrakuls extra turn.

Cool deck man! I like the idea but wouldn't the Aether Vial go 1 to 2, 2 to 4, 4 to 8, and 8 to 16? I think you need to have it 15 counters to cheat in a creature that costs 15 mana.

Yes, you would need to have 15 or more. I just said “1 to 2 to 4 to 8...” to let people know that you could go on infinitely past 8. I just stopped there because I didn’t feel like writing all that.

No I think it needs to be exactly 15. So my question is how do you get to exactly 15.

Wow, I never actually realized that. I don’t think you can. Hmmm... Well, I will try to think of a way to do that, but you could always just swap him and the other eldrazi Titans for cool 8/16 mana creatures. It would still work. Or you could just Umezawa's Jitte or something to win.

Umezawa's Jitte is banned in Modern.

Sorry for spreading this across two posts.

The card you want is As Foretold. Unlike Aether Vial, which must be the exact number, As Foretold can be used on any card with a smaller CMC than the number of counters.

One other important distinction - Aether Vial does not cast the creature - it merely puts the card on the battlefield. Thus none of the Titan’s powerful cast abilities will trigger with Aether Vial. They will with As Foretold.

You should still not be running so many large creatures. Some early game interaction interaction and card draw is a lot better than more bombs. Emrakul can win the game on her own - you do not need so much redundancy.

I know it isn’t legal in modern, but this is meant to be a joke/casual deck, so... As Foretold would work great here, as well as being cheaper. Thanks for the suggestions! I took out some big creatures for more Sphinxes, ‘cause infinite card draw is pretty cool.

You can choose Casual as the format, rather than Modern. That makes it a bit easier on those providing feedback.

I would argue infinite card draw is unnecessary. You have better ways to win. An early Opt is far better than holding yet another win condition, particularly as you might need to dig for your combo pieces.

I am/was going to do the whole casual thing. Yes, a card to dig for the combo pieces would probably be better than infinite card draw, but it is cool to have that too.
