Aeravok, Thunderstep Summoner

First Strike, Vigilance
Equip costs of cards you own on the battlefield
and in your graveyard cost {u}{r}{3} less to activate.
This cant reduce the cost of equip abilities to
below 1 mana.
You may cast equipment spells from your
graveyard by paying their equip costs. When you
cast a spell this way create a Thunderstep
creature token and attach it to this token.
