Gowen: new Yuni is just plain junk. I'm sorry, but let me get this straight--she's a level 3 with a rankup, and after rankup (which requires Gowen 6), she's just Mureria with another 10 attack? WHY IS SHE SO BAD?
New Dilate: him and Bringer, maybe? I still don't see in what file he would be specifically good. Some sort of gowen warriors? Except Gowen warriors suck, and 4 agility is rather average against files that like to rush you down (TJC is agi 5, buncles and SKs hit agi 6, dolls can regularly hit 5, and pack some nasty-ass effects at agi 4).
Roar of anger: worthless card. At what point will you be planning on dropping two units simultaneously? Even then, brave strike in a warriors file is just plain better.
Merc nation fencer: junk. Needs rankup to function, has subpar stats anyway, is random with her action skill, and gets bopped by 40 damage SSs. Is there anything redeeming about her?
Exploding wyvern: basically the reason to go Gowen this set. Like Sakura, its unit body is absolute junk. Yeah, tech units might be missing a stat point here or there, but if Refess is any indication, that's absolute nonsense (EXLap, buncle generals, Messala, list just goes on). No reason this guy shouldn't have had agility 5, and his action skill on close. What the heck do you do with his action skill anyway? Inferno of anger? All the burning cards completely and utterly suck >.<. Basically, as far as I see it, this guy replaces ball of flame in big red. With BKR/other mid gowens, you should be casting ball of flame as your units die off and LP becomes more of an issue than SP.
Ben Maclachlan: I really, really feel this guy is a joke. Basically, he reminds me of Refess's panoply of tanks, except will REALLY rock you if you're that dumb not to be able to kill a single level 5 that needs level 7 to rankup. But I suppose the idea is that if you have a field strong enough to reliably kill him, then you're just at that level to get rocked by Sakura, Allind, or Wyvern. If he were a level 4 with level 6 rankup with 20 less HP, he'd be very interesting. But apparently the testing team likes to have all the interesting units be so high level that they just get bowled over by entire fields of things, rather than work together.
