Isn't OnPoint a professional game designer?
I'd rather see a new Koth.
Koth, Geomancer 2RR
+1 Exile the top card of your library. If it's a land, you may put it into your graveyard and have Koth, Geomancer deal X damage to target creature, where X is the number of Mountains you control. If it's a nonland card, you may play it until end of turn.
-2 Destroy target land you control and target land you don't control.
-6 Return all lands from your graveyard to the battlefield. For each land returned this way, Koth, Geomancer deals 5 damage to target creature or player.
