Sharuum the Hegemon + Hashaton, Scarab's Fist

Sharuum the Hegemon

Hashaton, Scarab's Fist

How it works

1. Discard Sharuum in any way. Hashaton triggers, causing you to pay 2 to create a token copy of Sharuum that is a 4/4 black Zombie.
2. When the Sharuum token enters the battlefield, it triggers, returning the nontoken Sharuum from your graveyard to the battlefield.
3. Put the nontoken Sharuum into your graveyard due to the legend rule.
4. The nontoken Sharuum's enter-the-battlefield ability triggers, returning it from your graveyard to the battlefield.
5. Repeat from step 3.
