Kratos, God of War

Kratos gains Indestructible during the Combat
phase.
If this card becomes blocked by a creature an
opponent controls, you may pay {r}{r}. If you do,
give Kratos Double Strike.
If a creature dealt damage by Kratos this
turn dies, deal damage equal to that creature's
converted mana cost to its controller.
