In Scars of Mirrodin, my main interest has always been the articafts. But recently, I took out my old Geth, Lord of the Vault, and saw its potential in a new light. It is insanely strong and works very nicely with several cards. I’ll point out some that make a great combo.
Firstly, in the Scars set itself, the common Screeching Silcaw has very nice synergy with Geth. If you already control 3 or more artifacts, you can swing to put more fuel in your opponent’s graveyard for the fire that is Geth. Otherwise, you can use Geth’s artifact getting ability to get the Silcaw up and running.
On that note, Geth works very good with metalcraft permanents, especially if you don’t have many artifacts in your deck.
A combo that I think works pretty awesome is Geth combined with Zendikar block Bloodchief Ascension and Bloodthrone Vampire. Since Geth has intimidate, it shouldn’t be too hard to get 2 damage through three times. When the Ascension is active, every time you take out a card from your opponent’s graveyard, you get to drain 2 life for every card you mill. Bloodthrone Vampire is a funky sideshow, where you can sacrifice your opponent’s creatures over and over, bringing them back with Geth. By doing this, you keep powering your Vampire as well as milling your opponent and draining life if you have the Ascension active. (This gets really crazy if your opponent happened to have a Mitotic Slime in his or her graveyard)
Of course, the mana cost of Geth’s ability is pretty steep for repeated use on high cost cards, but a few Training Grounds should sort that out.
That’s all for now. Hm.
