Damn, so much to comment on. . .
Horribly Awry is probably bad.
Remove Soul is ok, not great. Not being able to stop big drops is going to be a big disappointment, I would just add the exile text to Remove Soul if you really want it, it isn't going to be too good.
Endless One is probably fine, the card is an easier to cast
Grenzo without the late game mana sink. Grenzo's body is really useful and this card will be useful too, just because when its in your hand it is any spot in the curve you need.
Wasteland Strangler is a stud, but does anyone have a cube where he is consistent?
Imagine if the green spell land threw the cards into the graveyard? As is, I'm not sure what to think. Probably terrible. The rest are all binder worthy.
Retreat to Valakut is an asskicking and a half, but its also a do nothing three drop so who knows.
How many land drops can you get during a game? Can you get enough so that retreat to Hagra is worth it? It is an extremely bad topdeck, but if you get it on curve it can wreck havoc. Drain effects are underrated. This card is extort
for lands.
Woodland Wanderer is a house. With three colors it is 5/5 trample/vigilance and pitches to force. If you get the fourth color it kills almost every creature in combat. No value whatsoever is a reasonably large limitation, but I think its over the line without feeling "removal checky".
Quarantine Field is funny. I mean, you think you a hero when you cloudpost it for 8 and sweep the board, but then they disenchant it and you feel like an idiot. Ring effects are cool, I guess.
