Dreaming of White Squeeze

Rather than pay the mana cost for a spell, its controller may discard a card that shares a color with that spell.

Lands you control are Plains. Nonland permanents you control are white. The same is true for spells you control and nonland cards you own that aren't on the battlefield. You may spend white mana as though it were mana of any color. You may spend other mana only as though it were colorless mana.

At the beginning of your upkeep, you may return this card from your graveyard to your hand.
