Akmon, Hammer of the Forge

Attacking creatures you control get +1/+0.
When a creature you control becomes blocked, it
deals 1 damage to each creature blocking it.
{t}: Target land you control becomes a 2/2
red elemental creature with
haste until end of turn. It is still a land.
At the beginning of combat, if you both own and control Akmon, Hammer of the Forge and a
creature named Koth, Volcanic Geomancer, exile
them, then meld them into Koth, God of Destruction.
