I'm on monoblack and I run one ensnaring bridge mainboard, so if I have it in my opening hand along with
a dark ritual AND I can empty my hand fast enough then I will play the game 1.
If not (99.9% of the time), I concede at the moment I know opponent is on Dredge.
Game 2-3 I board in
4 LotV : Against reanimator and dredge , I won't keep a hand without graveyard hate anyway, so Leyline is my choice for that reason alone.
3 Engineered plagues
1 Ensnaring bridge (I also play 1 mainboard)
1 NoSB (I also play 1 mainboard )
Out : Cards that make them choose the card they discard, Land destruction, taxing effects(trinisphere, Nether Void)
I mulligan into Leyline. That usually buys enough time to slam E-Plague on zombies, NoSB and ensnaring bridge.
They can't answer ALL these lock pieces so they lose, locked out of the game.
