Rowan, Scion of War + Exsanguinate + Unspeakable Symbol

Rowan, Scion of War

Exsanguinate

Unspeakable Symbol

How it works

1. Activate Unspeakable Symbol 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 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.

This clever loop turns your own life total into a lethal weapon by leveraging Unspeakable Symbol to pay 3 life repeatedly, driving up the discount provided by Rowan, Scion of War. Because Rowan's activated ability reduces the cost of black and/or red spells by the total amount of life lost that turn, paying into Unspeakable Symbol directly lowers the mana burden of whatever you cast next. You then cash in that massive cost reduction to cast Exsanguinate for a devastatingly large amount of mana, draining the entire table and instantly catapulting your life total back up.
