Overwhelmed Medium

Spirits you control get +1/+0.
Each non-Spirit Creature you control gains
Soulshift X, where X is their casting cost minus
one. (When this creature dies, you may return
target Spirit card with converted mana cost X or
less from your graveyard to your hand.)
"Some unfortunate souls are cursed with minds.
that so open, they force those of others to be so."
