This is a list I have developed for a 35 pt tourney I have coming up. I'm using the witch coven of garlghast for something a little different and hopefully to throw my opponents off a little.
Scenario is Gauntlet out of steamroller with 35 min deathclock.
Death Jack 12
Skarlock Thrall 2
Max Bane Thralls w/ UA 11
Warwitch siren 2
Basic idea use the stalkers to assassinate, or at least threaten their caster/lock all game to hopefully throw off their positioning a little. DJ runs up the middle causing problems where he can...which is everywhere. Defiler is there to extend my reach with the coven, maybe run in and spray some dudes if the opportunity presents. Banes walk up the middle and kill whats left over. Warwitch does her thing in support all game.
What do you think guys? Comments etc etc is more then welcome.
