Reins of Power + Sigil Tracer

Reins of Power

Sigil Tracer

How it works

1. Cast Reins of Power by paying 2.
2. Holding priority, activate all mana-producing creatures you control by tapping them, adding at least 2.
3. Activate Sigil Tracer twice by paying 2, tapping it and three other Wizards you control, copying Reins of Power twice.
4. Resolve the first copy of Reins of Power, untapping all creatures you and target opponent control, and exchanging control of those creatures.
5. Resolve the second copy of Reins of Power, untapping all creatures you and target opponent control, and exchanging control of those creatures, causing you to regain control of all the creatures you originally controlled.
6. Repeat from step 2.
7. If creatures you control can tap to produce at least 3, this combo nets infinite mana.

This delightful exchange begins with Reins of Power, which temporarily swaps control of your creatures and an opponent's while untapping everything in the process. To sustain this magical thievery, Sigil Tracer steps in as the engine's core, utilizing its wizard heritage to copy Reins of Power by tapping alongside your other wizards. Because the first copy of Reins of Power untaps your newly acquired forces, you are instantly restocked with more untapped wizards to feed back into Sigil Tracer's copying ability, looping the spell indefinitely to untap your board and generate infinite mana from any mana-producing creatures caught in the swap.
