Rowan, Scion of War + Stensian Sanguinist // Exsanguinate + Doom Whisperer

Rowan, Scion of War

Stensian Sanguinist // Exsanguinate

Doom Whisperer

How it works

1. Activate Doom Whisperer by paying life.
2. Repeat step 1 as desired.
3. Activate Rowan by tapping it, reducing the cost of all black and/or red spells you cast this turn.
4. Cast a copy of Exsanguinate, choosing for X to equal the amount of life you've lost this turn, but paying a total of due to Rowan.
5. Resolve Exsanguinate, causing each opponent to lose X life, and you to gain life equal to the life lost this way.
