Currently what I’m running, but still a WIP. Completely steamrolls silver though, basically no skill is involved with so many different options that work together perfectly. Mechs are decent tempo tools that also draw removal because of their keywords. Basic removal at 1 and 2 mana, 5 mana statsticks that also remove and everyone knows how good EMP is. Gameplan is to speed out mechs and get rid of the 1, 2, 3, 4 mana requirements for ox, while threatening to play z0r. Curve into 5 mana and control the board, run away on 6 mana and play z0r. Z0r will get removed and cost the opponent their whole turn, making it very easy to play EMP and ox on the same turn, securing the win.
SILVER + Metaltooth is a 8 mana 9 damage finisher if something goes wrong.
Play aggressive, but don’t spend all of your resources, and don’t suicide as you have no healing.
For the Abyssian mech combo, this is what I’d run, but it isn’t based on the combo itself, and it’s really just 2 mechs that got squeezed into Midrange. I also only play Cassy. Gain tempo with good 2 drops, one of the best 3 drops, and probably the most efficient single-target removal in the game. Drop threats with Dioltas, rot9m, b0t, grimes, and EMP to bash your opponent’s face in. Can’t guarantee this deck will even play z0r, and just might be better using SILVER for a better summon.
