Alberic III, The Evocator

First strike, menace
Whenever you cast your first instant or
sorcery spell each turn, you may cast a spell with
lesser mana value that shares a card type with it
from your hand without paying its mana cost.
If you don't, create Mini Hal, a legendary 2/1
creature token. It gains haste until end of turn.
