Minotaur Calf

As long as you control another Minotaur, Minotaur Calf gets +1/+0 and has trample.
{t}: Mature Minotaur Calf. Activate this
ability only any time you could cast a sorcery.
(To mature Minotaur Calf, exile it. If you do,
search your library for a non-Young creature card
that shares a creature type with it. You may cast
it by paying the difference in mana costs between
it and this creature. Then shuffle your library.)
