After playing around a bit with Henwen's Dimir Control I found that Counterlash into Griselbrand/Kozilek is an absolutely insane win condition, far more powerful than something like an Obelisk. If I could fit decent removal around that win condition I might have a monstrous control deck. This is a rough list I put together in about 10 minutes and I'd like some input on where to go from here.
The deck is almost all instants and sorceries, so Goblin Electromancer is a ridiculous ramp spell. It affecks all of our counterspells, card draw, removal, and with counterlash it means we can have a 4-5 mana Kozilek. It's mostly there because I want an early blocker against tokens, but with no other early creatures it might just be a removal magnet and end up pretty bad. I'm undecided.
I went with Negate over Nullfy because it's easier on the mana, it's affected by Electromancer, and I'm more scared of early Seance, Armored Acension, or Spider Spawning than early creatures. Against token decks countering a Kreko's Command or a Bident of Thrassa should be just as good as countering a random creature that dies to a removal spell.
I haven't really tested how it plays, I have no idea if the Radiant fountain is good or if the mana is right.
It's currently at 62 cards. Quicken seems quite good here so I'd prefer not to cut it, but I need to cut something. No idea what.
