Geth, Lord of the Vault

Using Geth as a general in edh is insane. Whenever people play mana booster artifacts you can bring them back from three and sac them again and bring em back. Geth''s ability does not cause him to tap, so if your bringing creatures from your opponents side theirs no need to cast anything from your hand and just keep building off others decks. Don''t forget to make people discard, his ability not only gets you cards but it also mils. If you have a sword of body and mind on geth you can end the game in quickly making them mil over 20 cards a turn or taking commander damage.

great to have unlimited mana if you opponent plays a black lotus.

Obviously, Geth will be a monster in Vintage. But in the current artifact-heavy Standard, he is downright god-like. There are so many cards you can steal and take advantage of to activate metalcraft, especially artifact creatures. Plus, he combos really well with many other cards. Geth plus Barrage Ogre won several of my prerelease games for me, allowing me to steal my opponent's Myrs and other artifact creatures and then sacrifice them to the Ogre to kill my opponent's creatures with infect. You need to have this guy if you're running a black deck in Standard.

Well I don't know if you will be seeing this guy in many Vintage decks soon, but he is a very cool card to combo with in various casual decks and especially EDH. He has many ways to be good but his ability is too situational for competitive play of scars standard. Put him in the right deck that mills your opponent a little bit or a black deck with lots of removal and he could be very strong.
