So this deck is based around both Heartless Summoning, as well as Grand Architect.
The deck is so ridiculously tech, its insane.
This deck won at the local FNM last friday, 20 APR 12
It took out the pro BR Zombies, pro UW Delver, 5 color control, BU Infect, Tempered Steel, UR Delver, BU Control
The possibilities with this deck are crazy.
Think turn two, heartless into a free 4/5 superion, or a free 0/3 Spellskite.
then into a turn 3 architect for BB, treasure mage for B, search for wurmcoil, and dropped in play 5/5 wurncoil on board, turn 3. its insane.
how about cycling through searching for lands, and then drawying?
2x Heartless summoning + Havengul lich + Solemn in yard, say pay 1 search for a basic, draw a card, for any ammount of mana you have open. at a cost of 1 colorless everytime.
or lets try shocking someones board, for the cost of 1 mana, over and over again. 6 mana open? perilous in graveyard, with heartless and lich out, thats 6 shocks, in a single turn. that can wipe board, or simply do 12 direct to your opponent, then pass turn, and next turn do it all over again.
try this one. Grand architect, treasure mage, spellskite say in play. with a wurmcoil engine. 5 mana, and drop 3 more wurmcoil copies, made by your phyrexian metamorphs. tap a mana turn spellskite blue. tap for 2 colorless, tap a mana pay 2 life, wurmcoil. tap architect, pay a mana, pay 2 life, wurmcoil. tap trasure mage, pay a mana, pay 2 life, wurmcoil. swing with wurmcoil, gain all life paid into playing the other 3 copies back.
The possibilities are amazing. these are just some of the things, i personally have done with the deck.
EDIT: This deck just won This past friday nights FNM as well. 27 APR 12. Beating out BW Tokens, Pro UW Delver, RU Delver, and Wolf Run. In 2 FNM, this deck has only lost 2 games in total, in all matches.
