Yeah, Radiant Fountain. Interacts with PLA well.

I've run UB Control since a week after PT Khans and have been doing a lot of testing with Crux and will say I'm not going to be running it at all. Has major issues due to its cost messing up the curve and not having the effect that vault has on the game which damage the deck significantly. So I wouldn't rule out UW running it over EH with similar effect. I would suggest running 2-3 Fountain, cutting Jace and running at least 27 lands and cut the second Evolving Wild. 4 Dig and 3 Ingenuity are a great balance for draw so might try that over what you have now. Plus they're both Instant unlike Divination and Interpret.

Oh I'm not saying have it automatically past the tags, just simply remove the tags if the deck isn't legal in that format.

No agreed but it is annoying when you're trying to find something and you get irrelevant results cause if out dated tags. Might need to suggest to the site that format tags check to see if the deck is legal in that format and self correct.

Well I doubt this could be reliable enough for serious contention but I'd suggest right of switching Shields for Ajani's Presence (same function with just a single W), cut Taigams completely it's just not a good card, remove 1 of each basic land and using those 3 spaces and the space from one of the Taigams add 4 Flooded Strand, with the 2 remaining spaces add 2 Disdainful Stroke. That should get you a little more reliable, might consider cutting the Confluences for Temple of Mystery since UG is the color pair you need most.

Just want to say first off you need to update your deck info cause you're mentioning cards you've removed. Second want to laugh at all the people who don't get how damage works. Hornets Nest triggers with any damage, deathtouch does work with fights, but first strike/double strike do not work with fights. I'm glad to see at least some people understood that and tried to explain it. Not a bad deck but it's more a casual fun deck than anything and pretty simple to break in competitive.

Remove the standard tag please once something leaves standard.

Here's my build for both Mentor and Soulfire.

Yeah see I'd say 4 taplands tops and have 21 lands instead of 18.

Not bad I like it, have you considered Akroan Hoplite? No heroic but can do insane damage. Otherwise I'd suggest cutting back on the taplands. Temples or Crags but not both, consider more basics or fetches if you have them instead.

You're never going to win with Grey Merchant ETBs alone, only get the trigger twice per merchant, and that's assuming you even get them to the graveyard. Once the whip is out no one is going to let you get them in the yard, they'll banishing light or suspension field them, or just exile them outright with devouring light or perilous vault. As for Master of the Feast I agree its a good choice in this deck but the rest of the creature base is so slow you're going to have trouble getting any damage to stick. They'll let the master in, and kill it as soon as they get a draw off it. After that the rest of the creature base is just not good. Overlord is decent assuming you can ever get enough devotion to make him worth it. Overall this deck has serious functional issues that'll cause you a world of problems.

Just the scry effect is useful, it's just going to be 1 Temple, I ran the list through my app after commenting.

Hmm work on the curve, cut a whip and a Nykthos, add another Liliana, get Hero's Downfalls instead of asphyxiate. Try to move the creature base to a more aggro form. 4 Bloodsoaked Champions, 4 Master of the Feast, 4 Squelching Leeches, 4 Grey Merchant, and 2 Overlords. Cut the Empty the Puts, run 2 Murderous Cut, 2 Despise, 2 Sign in Blood, 4 Bile Blight, and fill whatever space is left with Temples and another swamp.

Ok wondering what's with the red splash for just Keranos, and on that topic both Keranos and Sphinx interact horribly with Vault, if you're trying to win with Keranos you cannot vault at all, and if you play him late enough to not need to vault you won't have enough cards left to win off his triggers. Same goes for Sphinx, dies every time to vault. It's why the PT Sphinx deck didn't run the vault.

@Ninjastyle612 Way to go calling out that moron, I agree completely with what you said about PLA, and I get the running 3 Dig over 4. I personally run 4 Dig, and no Murderous Cut in my UB Control build, but I'm running a much slower game than you I think. I've got 3 Nullify, 2 Negate and 2 Drown MB, and my 3 Thoughtseize in the SB. PLA is just so good and anyone who thinks they're going to be playing it early enough to set themselves back if they have to bounce it is just wrong. I've never played it before turn 12, and even that's early. I've had games where I was at 10 cards left in my library before it came out to win. Only time I'd say Sphinx is better might be in a mirror game where they can discard for hexproof with your spot removal and counter the vaults.

You really should dump the Tormented Hero for Gnarled Scarhide, just a better creature. Also cut Athreos and run a set of Downfall and Blights instead.

Run a set of Springleaf Drum, gives you 1 drops, ramp, and a way to use King Macar without attacking.

You should really take a look at the Sidisi-Whip decks that are showing up, similar to this bit much more dangerous and filled out. This deck is going to run into major issues of you get hit with Drown in Sorrow or Bile Blight.

Umm yeah, not standard legal at all. Return to Ravnica block and M14 cycled out in September.

Could I simply point out that GR not seeing play isn't completely correct. It might not be getting the attention of say Jeskai Burn or Abzan Midrange but it did just win GPLA and GR Devotion is showing up pretty consistently. Oh and even if you're aggro running Courser/Caryatid in any green deck should be a serious consideration. Maybe not as 4 ofs but 2-3 of each is still a major advantage. I'd suggest setting up some of the other key GR cards like Stormbreath and Hornet Queen in the sideboard for if you find yourself needing to play a long game. Otherwise looks good.
