Clefable & Gengar

Deathtouch, Swampwalk
Whenever Clefable & Gengar deals combat
damage to a player, detain each nonland permanent
that player controls with mana value equal to or
less than the amount of different card types among
cards in your graveyard.
curse - If a source an opponent controls would deal
non-combat damage to a creature you control, it
deals that much damage to each other creature you
control.
