Rageblood Berserker

Other Berserkers, Barbarians, and Warriors you control get +1/+1.
The berserk ability of creatures you control costs {2} less to activate. (This affect doesn't reduce the
amount of colored mana you have to pay.)
"These Norskans live by one simple rule: If you go
down, take someone down with you."
— Saskia of The Aethelingas
