Whenever one or more squirrels you control deal combat damage to a player, that player exiles a
card from their hand at random. Until end of
turn you may cast that card and spend mana as
though it were mana of any color to cast it. If you
don't, return it to it's owner's graveyard at the
beginning of the next end step.

token.
