Armor of Noc'thril

Equip {1}{b}{b}{b}{b}
Equipped creature gets +8/+8 and whenever equipped creature becomes blocked, target creature takes damage equal to equipped creature's power.
When Gideon banished Noc'thril, He wasn't aware of the blessed armor
in the Lair of Noc'thril, and now Noc'thril's soul rests in that suit of armor.
