Just got done playing the black white eldrazi build to a top 8 in a 20 person gpt. I honestly think it's just straight up better than deadguy ale. The game basically rests on if you draw the correct lands though. When you do it's absolutely bonkers. When you don't you just kind of wait to die :\.
To be fair dga isn't exactly rogue. It won several modern states last year and has been putting up decent results since roughly the inception of modern.
One thing that is often overlooked though in this thread is that mana tithe has been in the most sucessful builds.It has been more or less ignored and I think I'll start giving it some more testing time. It plays exceptionally well off of the fact that we have path.
I've actually played a lot of blood ghast decks in my life unfortunately I don't think this is the right strategy for him.
Historically bloodghast has been played in 3 types of decks.
1.) Aggressive decks b/r vamps ala scars zen standard
2.) Combo(ish) decks that can take advantage of multiple free creatures in a turn (aristocrat style decks)
3.) Sideboards of control decks for the mirror.
Dead guy is slower than #1 has less synergy that #2 and has too many threats to be considered #3.
I think the only thing holding him back is the inability to block. The combination with war gear is neat but remember to consider the average and worst case scenario. Sometimes you'll have aghast without a gear and all you accomplished was discarding a card that probably wouldn't help your plan anyway.
3 wargear is probably too many. Tasigur is going to murder your face off from Dark Confidant, also since you can't activate his ability if you really wanted a delve card you should go with tombstalker or gurmag angler(I would say no to both) In general though your curve is too high to play dark confidant without being afraid of killing yourself.
Saying vault and shambling vent are accomplishing the same thing is a gross oversight. The death touch aspect of vault makes you're opponents life hell since that of activation when attacking and it turns all of your souls into removal spells.I feel gideon lends himself much better to be tokens than us.
Packrat isn't a great card but the upside of it is that a lot of pure cards are good early and useless otherwise. The allure of packrat(and the reason I'll never cut it even if we do get mystic) is that turn 9 thoughtseize draws are never completely dead in the deck. There are plenty of other grindy creatures but none of them give you this kind of outlet for your cards that suck in the late game.
I think the biggest difference is that tokens has a much more aggressive game plan than we do. DGA is all about attrition and card advantage, because of this we are generally better against combo decks as we play more interactive spells. This also means our clock isn't nearly as good so we concede to needing main deck life gain in some fashion out a way to speed up or click that isn't generally considered excellent(grafted wargear or sometimes swords) recently we have been including abyssal prosecutor because it stabilizes the board and is immune to the most common forms of removal in the format then once you have stabilizes the flample helps close out the game quickly.
I'll throw my 2 cents in for your questions Bjamman.
1.) I think the deck DOES have enough fuel for tasigur but the biggest problem is messing up the mana to get the extra abilities out of him. If we weren't playing Bobs we would pobably play anglers instead. As far as Jotun grunt goes I feel he has quite a strong matchup against tasigur mostly because he makes it really damn hard to cast the 4/5 and a 4/4 vs nothing is pretty strong.
2.) The trample of abyssal is absolutely the reason I want him over desecration. He also has won me a lot of games by just being a blocker people can't swing into where as with desecration they can simply sac their worst and swing through with their best (Abyssal persecutor is an Abyss for the best creature they're willing to swing with while Desecration demon is an Abyss for their worst) On top of all that I've never saved removal for persy instead of killing an opponents threat. Usually we will have enough time due to vault or sorin to just naturally get to removal after our opponents are at 0. Quite frankly though I'd rather have 4x lingering souls than any number of aetheros in my deck.
3.) Aetheros is a good card in our colors but I don't feel like it fits our strategy. Perhaps if you played arenas instead of Confidants it would be good (this would also allow you to play gurmag angler.
