Quote from JamesTheIV »I also started with 99 mountain Ashling and built from there. Never put it down. Still my favorite EDH deck. I'm currently at close to 60 lands. Ive ran more spells but took a lot back out. I like to dump as much mana into Ashling as possible and only use mana otherwise for essential spells that increase how threatening Ashling is. I put pressure on players early with commander/combat damage from a large Ashling but always have mana open to threaten blowing up the board and doing a lot of damage to players if me or any of my essential permanents are targeted. I play very political. My build is currently more of a rattlesnake / voltron build than a controlling one. I try to finish the game with a big burn spell via comet storm or chandra's ignition.
I like the inclusion of Walking Ballista. Going to pick one up for my deck now. I would highly recommend extraplanar lens & heartstone for your build.
