Turn 1 -Play an Island or Plains -Tap land and play Springleaf Drum -Cast Ornithopter -Tap Springleaf Drum to tap Ornithopter to produce 1 mana and play Altar of the Brood.

Turn 2 -Play land -Tap two lands, tap Springleaf Drum to tap Ornithopter to produce 1 mana (at least one of these mana need to be white) and play Midnight Guard

Turn 3 -Play Retraction Helix on your Midnight Guard -tap Midnight Guard to bounce Ornithopter to your hand -Play Ornithoper -Repeat steps 2 and 3 of turn 3 until all opponents are milled hopefully holding a Negate/ Gods Willing /Stubborn Denial to protect the combo. -Pass the turn and enjoy your opponents losing on their Draw.

If you cant get the combo off you have indestructable 5/5's thanks to Darksteel Citadel and Ensoul Artifact. With Taigam's Scheming and Divination you can dig for the combo.
