I also have full play sets of The Scorpion GodBloodsoaked ChampionEarthshaker Khenra and Temur Battle Rage. I'm hoping Mogis and kill spells can keep the board fairly clean until Dragonlord comes out then the opponent will really have to think about playing a creature since if a copy is in the grave yard they'll lose 10 life. But I do think Wheel of Fortune would be a good addition for if its the only card in my hand to force them to discard and I get to refill my hand, hopefully with more kill spells.
Working on a new Red/Black deck with Dragonlord Kolaghan and Mogis, God of Slaughter. Gonna be using cards like Terminate and Dreadbore to help clear the board for Kolaghans secondary ability to keep creatures in check once he hits the board but any other suggestions for creatures/spells would be appreciated.
