Rein, of Clan Ornzar Bloth

Whenever a creature you control deal's damage to
a player, venture into the dungeon once per turn.
At the beginning of your main phase, create a
artifact equipment token with equip(2) and
equipped creature get's +1/+1 and one keyword
choose between: first strike, trample, vigilance,
or menace, then attach it to target creature.
If you've completed a dungeon, equipment you
control cost (2) less to equip.
