Rograkh, Son of Rohgahh + Myth Unbound + Mirage Mirror + Yahenni, Undying Partisan

Rograkh, Son of Rohgahh

Myth Unbound

Mirage Mirror

Yahenni, Undying Partisan

How it works

1. Pay 2 to Mirage Mirror to have it become a copy of Myth Unbound until end of turn.
2. Cast Rograkh from the command zone by paying 0.
3. Activate Yahenni, Undying Partisan by sacrificing Rograkh, returning Rograkh to the command zone.
4. When Rograkh enters the command zone, both copies of Myth Unbound trigger, causing you to draw two cards.
5. Resolve the Yahenni, Undying Partisan ability from step 3.
6. Repeat from step 2.

This ingenious loop turns your free commander into a self-sustaining engine by cleverly stacking replacement effects and clever cloning. Because you can cast Rograkh, Son of Rohgahh for zero mana, you can immediately feed it to Yahenni, Undying Partisan to send the kobold straight back to the command zone. This triggers the card-drawing ability of Myth Unbound, but the real magic happens because Mirage Mirror has been temporarily turned into a second copy of Myth Unbound—meaning every single trip to the command zone rewards you with a double dose of card draw.
