I really want to have something less... unstable than mono green infect IRL. Seeing as the current Standard Grixis Control deck is good, I figured I'd try to adapt it to Modern. Modern has more powerful finishers but I still believe AEtherling is the best of them. You cast it and you win the game 90% of the time. With that said, I'm just missing the shock lands, but I'll be getting them soon. With those, this is the decklist I currently have:
2 AEtherling
1 Wurmcoil Engine
1 Grave Titan
1 Inferno Titan
4 Gitaxian Probe
4 Go for the Throat
4 Lightning Bolt
4 Mana Leak
4 Think Twice
4 Thoughtflare
1 Blasphemous Act
1 Dissipate
1 Tribute to Hunger
1 Jace, Architect of Thought
1 Nicol Bolas, Planeswalker
4 Steam Vents
4 Watery Grave
3 Blood Crypt
3 Dragonskull Summit
3 Drowned Catacomb
3 Sulfur Falls
2 Island
2 Mountain
1 Cascade Bluffs
1 Swamp
2 AEtherling
1 Wurmcoil Engine
1 Grave Titan
