Screw all these discussions about obviously good characters (Asstrid, Hilde, Jin) or absolute garbage characters (Yi Shan), let's talk about those characters who have a hard time fitting in, and see what we can find...
I'm talking, of course, about:
Astaroth
Siegfried
Temujin
Zi Mei
Astaroth-
So, yeah, I've been clear on how useless I find Astaroth, but after viewing ways to abuse him, he's really not TOO bad. Off of Earth, you can abuse the Hell out of Maniacal Laughter to blow up your staging area, getting more pump for Asta, Stunning their stuff, and momentum for Hades Destroyer. Off Evil you can just use Intimidating Presence instead and G-Corp Leader so you don't truly lose what you blow up. Driven by Fear for finishing touches.
He has some OK kinda tricks with Kulutues* (good in conjunction with actions, like No Forgiveness!, Base Hold, etc), and of course, has a Powerful: 2 Throw.
I'm a bit more drawn to the ogre than I thought. Kulutues in conjunction with Maniacal Laughter to blow up committed stuff then using Astaroth's own ability makes for some stupid big damage pumps, especially when combined with his Terrain which is just aggrosauce.
Way to run: I'm not entirely sold just yet. I'm looking into Earth as his best option, but Fire has Driven by Fear and Knight Breaker.
Siegfried-
Mr. Reliable is just...too one-sided. Besides symbol shenanigans with Needs no Ally, he's just a very solid beatstick. At +4, you're almost guaranteed to pass it for free, generally 3-4 damage, and even if you have to commit 1, that's well worth it. As such, people often say he's a Throwdown char, packing Embrace, Flooded-Nile, and Close Throw with No Forgiveness!, but really, I feel he has a bit more potential than that.
Once again I'm siding with the Mountain on this side, I think Sieggy's Earth game helps him maintain his aggressive prowess. Of course, off of Life, you've got some more technical means, such as Knows When to Talk, Genius Alchemist, Eiserne Drossel, Hunt for Jin, Menuett Dance, etc.
Siegfried definitely seems fun, but my main issue is trying to justify using him over any other Earth aggro character (such as Ragnar, King, etc).
Temujin-
After seeing Temujin, I looked forward to building him. Of course, the harsh reality I quickly learned is that, really, it's just hard to justify running him. To me, his F is his crowning jewel, but there just aren't enough combos to make it matter. The only true saving grace he has besides his own abilities is his Descending Dragon Spear, which, to me, isn't as good as Midnight Launcher.
His E, also, I find kind of useless, because by the time you play attack #3, especially in Temujin, it's likely to be a combo, if not a game-winning Combo.
He isn't useless, but I'm just having a hard time justifying his use. I understand when Arrayed for Battle comes out he'll be a tad more, well, better, seeing as how -3 to your next Combo (or just use Trained Far and Wide) will definitely help pass multiple combos in a turn, but between Nursing a Grudge (requires damage dealt) and Forgotten Technique (requires momentum), I just have a hard time using him, even off Fire.
Zi Mei-
To me, I can only really define her as "I can play a big fricken Fury of the Ancients", which if it ever rose in popularity again, people would side Mark of the Beast. Anyways, Zi Mei I find to be the HARDEST character to build only because, once again, her character-specific abilities are so hard to utilize. Determined to be the Best just isn't very good. Ascending Zephyr is just flat-out good in anything requiring momentum that has Chaos (Steve Fox primarily =D). Autumn's Kiss has a better E IMO. And Fury of the Ancients is, well, her main saving feature.
To me, again, it's kinda hard thinking about using Zi Mei because of her R, because by that point, there are likely better characters. She has a nifty Enhance, but Ivy does 3 damage or less better than she.
As far as a hypothetical Zi Mei build goes, I considered using her off Air. I had Wipe the Floor and Shockwave Palm to try to discard their hand, Wheel Kick to cover their board, clear the field with Driven by Fear, Fury of the Ancients, Zi Mei E on the card, Zi Mei E Commit 2 foundations, Autumn's Kiss E, Mulitple 7 from staging area + momentum.
However, that was the only clever strategy I had, and it was both susceptible to anti-discard AND anti-multiple (and Calming the Mind).
So, in short, I'm having immense fits trying to justify using Zi Mei.
