The deck is built for modern, simply because its my favorite format.I'll start with a bit card discussion
Utility creatures:
Grand Architect: He'll help to bring CMC6 stuff out on turn three or four, which is pretty fun. He also can neutralize the -1/-1 from Heartless Architect if he makes the artifact beaters blue.
Treasure Mage: Will search for Wurmcoil Engines, Steel Hellkites or Sharding Sphinxes, based what I need and can then tap for the Architect.
Phyrexian Metamorph: Basically copies one of my beaters (or one of the enemy's) but it's also able to kill legendary creatures of my opponent if it really has to. Since they depend on my beaters to be around, only two of them get in.
Spellskite:They will save the big guys from spot removal and maybe block some early attacks. If casted heartlessly they also cost nothing, which is always nice. Two of them aswell.
the beaters:
Wurmcoil Engine: My favorite beater and probably the most attractive target for Treasure Mage. Two copies will do.
Steel Hellkite: Often inferior compared to the Wurmcoil Engine, but in some cases it might be the better choice.
Sharding Sphinx: This one is very situational and depends heavily on my board. If theres an Architect its awesome, because the (blue) tokens get bigger. If theres a Heartless Summoning its just bad since the tokens will all just die. I'll put one copy in, so that i can search it with a Treasure Mage if the board position is right and discard it with Thirst for Knowledge if the board position would make it useless.
Myr Superion: It can be the earliest win condition in the deck, but it might aswell sit in my hand doing nothing, since it depends on either the Architect or Heartless Summoning being in play. Still lovely, I find.
the noncreature spells are pretty self explanatory:
Thirst for Knowledge has enough artifacts to make it work and can get rid of unwanted Hearltessness later on.Remand, Mana Leak and Go for the Throat should buy me some time and Heartless Summoning simply does what it does.
