Rowan, Scion of War + Thermopod + Deekah, Fractal Theorist + Seething Anger

Rowan, Scion of War

Thermopod

Deekah, Fractal Theorist

Seething Anger

How it works

1. Activate Rowan by tapping it, reducing the cost of all black and/or red spells you cast this turn by at least 3.
2. Cast Seething Anger with buyback by paying due to Rowan's ability, targeting any creature.
3. Deekah triggers, creating a 0/0 Fractal creature token, then putting a +1/+1 counter on the Fractal.
4. Resolve Seething Anger, giving target creature +3/+0 until end of turn and returning Seething Anger to your hand.
5. Activate Thermopod's second ability by sacrificing the Fractal, adding .
6. Repeat from step 2.

This clever loop turns the self-inflicted life loss from Rowan, Scion of War into a torrential engine for infinite storm and massive creatures. By tapping Rowan, you discount your red and black spells by at least three life lost, which allows you to cast Seething Anger for a mere single red mana despite its buyback cost. Every iteration triggers Deekah, Fractal Theorist's magecraft ability to churn out growing Fractal tokens, which you can immediately feed into Thermopod to generate the red mana needed to recast the spell and keep the loop spinning endlessly.
