Beserker's Rage

As an additional cost to cast this spell, sacrifice an artifact.

Target creature you control +X/+0 until end of turn, where X is equal to the converted mana cost
of the artifact you sacrificed in order to cast this spell. If the artifact sacrificed was a token, instead target creature gets +2/+0 and gains indestructible until end of turn. (Damage and effects that say "destroy" don't destroy it.)
