Black Lotus Unknown Planechase

When you encounter this, Each player opens a Magic the Gathering booster pack. They may select up to two cards from that pack and exile them face down. For the rest of the game, players may look at and play cards exiled this way without paying their mana costs. (Then Planeswalk away from this phenomenon.)

Whenever you cast an animal spell, draw a card. (Animals are any non-human creature types that are animals in real life.) Whenever Chaos ensues, create a token that's a copy of target creature you control, except it's a 1/1.

When you planeswalk here and at the beginning of your upkeep, create a Tulip Petal artifact token that has "T, Sacrifice this artifact: Add one mana of any color." Chaos: Spin this plane until the arrow lands on a permanent. If the plane rotated at least 360 degrees during the spin, create a token that's a copy of that permanent.

Each player may choose a nontoken creature they own on the battlefield, reveal a creature card from their hand, or choose a creature card in their graveyard. Those cards become promoted to commander. Each player may put their new commander into the com- mand zone. Then planeswalk away from this phenom- enon. (All original commanders are still commanders.)
