The Cave of Two Lovers - Avatar: The Last Airbender

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)

I — Create two 1/1 white Ally creature tokens.

II — Search your library for a Mountain or Cave card, reveal it, put it into your hand, then shuffle.

III — Earthbend 3. (Target land you control becomes a 0/0 creature with haste that's still a land. Put three +1/+1 counters on it. When it dies or is exiled, return it to the battlefield tapped.)
