White Dragon

Flying
Cold Breath — When White Dragon enters, tap target creature an opponent controls. That creature doesn't untap during its controller's next untap step.

Village Rites

As an additional cost to cast this spell, sacrifice a creature.
Draw two cards.

Ephemerate

Exile target creature you control, then return it to the battlefield under its owner's control.
Rebound (If you cast this spell from your hand, exile it as it resolves. At the beginning of your next upkeep, you may cast this card from exile without paying its mana cost.)

Eliminate

Destroy target creature or planeswalker with mana value 3 or less.

Strategic Planning

Look at the top three cards of your library. Put one of them into your hand and the rest into your graveyard.

Don't Have

Growth Spiral

Draw a card. You may put a land card from your hand onto the battlefield.

Cultivate

Search your library for up to two basic land cards, reveal those cards, put one onto the battlefield tapped and the other into your hand, then shuffle.

Memory Lapse

Counter target spell. If that spell is countered this way, put it on top of its owner's library instead of into that player's graveyard.
