Morgoth’s Mastery

Incantation 4 — {3}{u} (You may pay {3}{u}, and
exile four cards from your hand rather than paying
this spells mana cost. If you do, it can`t be countered.)
Gain control of target creature with converted
mana cost 4 or less, then take an extra turn after
this one. Exile Morgoth`s Mastery.
