Planar Warming

Exile all snow permanents.
For each snow permanent exiled this way, its controller creates a Wastes token with "{t}: Add {c} to your mana pool." that counts as a basic
land.
"Planar warming is nothing but a Selesnya conspiracy
to keep the Izzet down. It's not real." -- Ral Zarek,
Izzet Viceroy
