Snap

Swarm Intelligence

How it works

1. Activate up to two lands by tapping them, adding at least .
2. Cast The Master either from your hand or from the command zone by paying and commander tax, if applicable, choosing to have it enter the battlefield as a copy of Archaeomancer.
3. When The Master enters the battlefield, it triggers, returning Snap to your hand from your graveyard.
4. Cast Snap by paying 1, targeting The Master.
5. Swarm Intelligence triggers, copying Snap, targeting Ornithopter.
6. Resolve the copy of Snap, returning Ornithopter to your hand from the battlefield, and untapping up to two lands.
7. Activate up to two lands by tapping them, adding at least .
8. Resolve the copy of Snap, returning The Master to your hand from the battlefield, and untapping up to two lands.
9. Repeat.

This cunning loop turns a single spell-copying engine into an infinite engine of mana, casts, and bounces. With Swarm Intelligence amplifying your plays, every bounce spell effectively splits into two targets: one copy clears away a cheap artifact creature like Phyrexian Walker, while the other bounces The Master, Formed Anew: Body Thief. Because The Master enters as a copy of Archaeomancer, each return pulls Snap right back to your hand from the graveyard, and the lands you tap to fuel the cast are more than untappingly refunded by Snap's resolution.
