"you are going to fight against Kiki Cr and Imperia Sloane/Miss Sloane at the same time, with Arno and who knows which one more"
Yookie, Jeena, Zatman Cr and Jackie cR, Rex Sweig, Yayoi cr; Chopper ld, Mina and Brody because of course the AI doesn't have the restrictions on abilities we have to deal with.
When I wrote that, I pretended to say another character, probably quite good, but in fact it really doesn't matter because of the other 3 you are f****d up.
But yes, one of my "favourite" combats was against Clover, Clover Noel, Yayoi Cr and Brody and I had no SoA (not the hand, yes the deck)... so let's guess in which of my turns will AI uses Brody with fury. Well that's not true, AI uses Brody when I start and don't cover the play, or the other round when I don't have pillz. Yes, that happened to me, both things.
But the Miss Sloane, Arno, Jeena, Yookie it's nice too, and I fought that a couple of times, and at least I'm going to face it at least 1 more time probably X-D
Anyway, I couldn't complete Hardcore mode of the 12th HQ (my superluck in the last 2-3 combats it's even worse this time), so I decided to complete the 13th first to avoid extra frustration as I did with other HQs before, and now I'm worse. This HQ goes too far, first the combination (Uppers+Raptors+Pussycats is tough, and combined with Roots is a damn beast), and then the characters the AI uses... as you said, the AI doesn't have our restrictions, and abuses them as much as possible combined with high power characters and/or really good DR, of course some of them we can't use either.
PD: Now Clover, Clover Noel, Yayoi Cr and Jackie Cr, Chlora, Doug Snop, Graff and Kreenk Ld... few damage, but I managed to win 8-7. And just the 6the combat (more or less).
This might help those who are trying to finish the Hardcore mode: I used a mono Riots deck, and I lost only once on the 8th stage, then on my second attempt, I completed it in like 25 minutes.
Boomstock, Daphne, Fastbender, Grace, Greendy, Grouchy, Lenora and Pr Balthazar.
The AI gets very confused against pillz manipulation, so it wastes lots of pillz in one single round. You can use Argos or Geo instead of Greendy but I think the rest of the deck is pretty obtainable. Daphne is especially strong in this deck -lots of fights against the Roots as well as Yayoi Cr etc- so try to use her +16 against the strongest SoA cards (Kiki Cr:weird.
Hope this one helps everybody who is trying to complete the HQ. Good luck!
I managed last night to accomplish the hardcore mode with Bangers. But that was really hard to me, maybe you'd prefer to try the deck Ulas posted before you.
Anyway, I've used: Bodenpower, Chlora, Doug Snop, Graff, Kreenk Ld, MC Leroy, Randal and Tasty Tast. In some fights you'll have to use fury to win due to the lack of damage, but if I could win, I'm sure almost anyone can.
For me... I'm missing 1 star, the 12thHQ's hardcore. My "usual" clans don't work fine (Uppers and Junkz). I tried yesterday what Ulos posted, just in case, but... Surprisingly despite this 13th HQ is harder, the last star for me is the 12th one X-D It seems that by now Huracan are my best shot, until I fed up and try the clans I haven't tried.
Hardcore (and arcade in general) is a joke. way too many handicaps, many perfect or good responses (obviously a cheat from the game), not so good rewards anymore (no cr). the game obviously wants to make us desperate in order to spend credits on this farce, but i just leave this thing aside.
in the next mode you release, try harder and think smarter.
Use Huracan for stages without Raptors (Montana might be good as well). Use Bangers for stages with raptors (with pillz manipulation). Finished hardcore in just 2 attempts. Something that can get past DR is important (SOA, Protection: Damage, - Opp life, etc)
