Cadric, Soul Kindler

Rograkh, Son of Rohgahh

Cloudstone Curio

Phyrexian Altar

How it works

1. Cast Rograkh either from your hand or the command zone by paying 0 and commander tax, if applicable.
2. Rograkh enters the battlefield, triggering Cadric and Cloudstone Curio.
3. Resolve the Cloudstone Curio trigger, choosing not to return anything to your hand.
4. Resolve the Cadric trigger, causing you to pay 1 to create a token copy of Rograkh with haste.
5. The Rograkh token enters the battlefield, triggering Cloudstone Curio, returning the nontoken Rograkh from the battlefield to your hand.
6. Activate Phyrexian Altar by sacrificing the Rograkh token, adding 1.
7. Repeat.
