MTG Salvation

Interesting card, however you need to have a lot of mana to make it tick (unless you have infinite mana) and it is totally reliant on opponent's GY. Not sure I would ever use it, but it could perhaps fit in my Lazav edh deck.

This card existing is a nightmare for Combo, because now any deck running UB can steal your combo after controlling the game to a certain point. And playing it in the mirror match is just evil.

Interesting card to say the least. It's basically yawgmoths will but for your opponents graveyard. Not sure how usefull this will be because in older formats, when your opponent starts cracking it's lotus blooms, etc, they will be going off that turn anyways. Not giving you a chance to cast this. In fair decks, I don't really see this being played

OH HAI YAWGMOTH!

This card seems like a lot of fun, problem is the natural home of something like this would be some sort of hybrid ramp/mill edh deck. I'm not sure how good it is to just shove this in a UB deck because you're never going to have much mana to get real advantage out of it.

Sultai ramp finisher?

Despite this being a very powerful effect, it's unlikely to ever be more than a cheeky sideboard card. Even with lots of mana, you're at the mercy of your opponent's deck value in relationship to the board state. Could be fun though against the right decks, especially in tandem with a strong removal theme. Also, that art is phenomenal.
