Relentless Rats

// Creature [28]

4 Birds of Paradise

24 Relentless Rats

// Artifact [8]

4 Door of Destinies

4 Thrumming Stone

// Enchantment [4]

4 Bloodbond March

// Land [20]

8 Forest

12 Swamp

60 cards

Best turn-by-turn play:

1. Forest, Birds of Paradise
2. Swamp, Birds of Paradise
3. Swamp, Thrumming Stone
4. Swamp, 2x Relentless Rats (thrumming into tons of rats)
5. Swing for the win!

Other possibilities include dropping a turn 3 Door of Destinies, then start playing rats till you get a stone. If you lose your rats (say, to a Maelstrom Pulse), dropping the Bloodbond March can bring them all back. Of course, a single Thought Hemorrhage will ruin this deck's day.
