Exile any number of historic cards from your graveyard with total mana value 30 or greater: You get an emblem with "Creatures you control have base power and toughness 9/9."

Each creature card in your graveyard has scavenge. The scavenge cost is equal to its mana cost.
Whenever chaos ensues, create two 1/1 white Warrior creature tokens.

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.

{T}: Add one mana of any color.

Whenever day becomes night or night becomes day, you gain 1 life. You may draw a card. If you do, discard a card.

At the beginning of your end step, if you didn't activate a loyalty ability of a planeswalker this turn, you lose 2 life.
