Drifblim

You may sacrifice a creature named Driftloon
rather than pay this spells mana cost.
Flying, protection from Warriors and colorless
creatures that are nonartifact and nonSpirit.
Soulshift X, where X is the number of cards in
your hand. (When this creature dies, you may
return target Spirit card with mana value X or less
from your graveyard to your hand.)
When Drifblim is put into a graveyard from
anywhere, target creature gets -0/-2 until
end of turn.
