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.
With a card like Dragonlord, I would look into sending your opponents cards to the graveyard as fast as possible. I would think about a Millstone type deck. Cards like Dark Deal would be interesting but it hits you too. Wheel of Fortune is an oldie but goodie. Chandra Ablaze is a repeatable replacement. Key to both is to reduce your hand to zero before firing them off. I'm not forgetting creatures but Black Cat is all I can think of right now.
One problem you might run into are dredge opponents who want their library in their graveyard.
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.
What format are you targeting? Can't be EDH.
