Plane of Thought

Companion — The sideboard of each opponent
also includes a card named Plane of Thought.
At the beginning of your upkeep, if
Plane of Thought is outside the game, instead of
drawing a card, you may search your library for a
land, reveal it and exile it, then shuffle.
If you do, create a Thought Construct land token
with"{t}: add one {c} ; and {t}: exile a land from
your hand. If you do, draw a card."
If no land was exiled that way, draw a card.
