Hexproof, Soulbond
Can soulbond any number of creatures.
They get +1/+1 for each paired creature.
You play cards from your graveyard. They
cost {1} more. Cards you cast from your
hand cost {3} less. Put a kid counter on The
Mind Flayer during your end step. When it
has 2+ kid counters, it loses hexproof.
