Rhydon

Whenever Rhydon attacks or blocks exile
target creature card from a graveyard.
When Rhydon dies, choose one of the exiled
creature cards and place it face down. You may
look at and play the exiled card for as long as it
remains exiled. You may spend mana as though
it were mana of any color to cast that spell.
