Apparently because of how the meta has shift into more of MP banish, lv.5+Ancient Wave+Angel+AW+Gabreit proven to be inefficient against most current meta matchups. Still the same problem as ever, Umr's SIGNIs are so vulnerable against everything that it's so hard to keep a 12-limit board making Ancient Wave a cost 1 Bloody Slash most of the time.
Though, most of them will be fixes "IF" Ancient Wave can trash any SIGNI and Ultim's Exceed can uses On-Play.
Playing Chaos(w/ or w/o lv.5), spaming Hastur as much as possible to pay for Miasma or other good defensive ARTs and use Ancient Wave as an offensive tool seems to be a better way to play.
I also thought of a cheese build with 2 Ancient Wave, 2 Grave Rush and 1 Miasma so that you can take full advantage of Ancient Wave as a defensive ART. Didn't actually try it but sounds pretty cool so I put it here.
Still waiting for the day that Umr can do well against metas.
Oh and black Valk is pretty bad. Just save space for Archold if you plan to run any Valk, though she might be something in a pure angel build, twilight Tawil maybe?
Also, considering that Tawil 6 is better than Tawil 5 in general, that extra 3 mill early game isn't that necessary. From play testing, most of the time you milling early you will mostly get 1 angel(or 2 depending on the luck) and the combination of either servant or spell, which will hurts her more in the late game.
We were talking twilight Tawil here no? read: Tawil 5 with black Angels @1-2 copies or so as techs
Even at Tawil 6, filling the drop zone if your opponent managed to live for 2-3 turns (which in nowaday's late game with Spinner, APEXLORD and etc being defensive for you, will be considerably common) after you reaching level 6, you will run out of things in your trash to do things with, and Black Valk can help you in that regard. It won't happen most of the time, but that's why she's a tech. Plus, again, Nakirun and things to get her out exists.
Also Black Valk would be your ideal target via Michael when you don't have Nakiruns in deck anymore.
Twilight Tawil(angel build) actually was never seen in play, or I never saw one, hence I put in "maybe" in the original post.
I see. Your point is fair enough, however depending on the support I don't feel like playing twilight Tawil for now, 1 Valk does sound okay. Though the last time I build a Tawil deck, I rarely have burst space left especially that I run Hellboros and a few AW*.
I thought you're not up so I didn't feel like logging in because, well, public computer.
