Gruvela, Coven Matriarch

Whenever you cast your first instant or sorcery
spell each turn, create a 1/1 black cat creature
token. If its the second instant or sorcery you
cast, you may pay an additional {x}, if you do,
you may cast target instant or sorcery spell with
converted mana cost X or less from your
graveyard without paying its mana cost.
Sacrifice five cats: Until end of turn, you may
cast sorcery spells as if they had flash.
