Acrobat deck

[HereIsPlenty]

Finally beat Acrobat deck after a lot of tries. Kept hitting 2 wins only in sequence then finally got a 17 and realised how to play it. The earliest rounds are the hardest ones as you have least control but the key is buying a good second green skill, preferably the randomise one for 3 agility. From there your constant flood of green mana means you have more control over what happens. I also realised that my Alchemy strategy was all wrong on Acrobat. It mostly only works where you are getting the mana for your key spells from your cards but on the single mana colour decks, its almost a liability. With acrobat, once you are swinging, you can start to build long streaks and gain enough coin to buy better items.

I was using at the end Siamese cat to reduce all attack damage by 1, Oboe to give all heals +2, the 2 and 4 healing items and the +3 and +4 health items.

Got to Emperor Stuck and had him down to 1 card twice before he cascaded more and more cards on top of me. Finally beat him with all 3 extra lifelines unused.

Green main decks rely on combo card clearing to devastating degree, yes. I haven't played Acrobat yet, because even after winning a class I stay with it till I learn it fully. After I learn a class fully my win rate in normal mode goes up to ~98% (and the other times I'm usually extremely tired). Right now I'm playing wizard which I've won a few times and have learnt quite a bit about, but haven't done so fully.

So far rogue and wizard have trouble on Lord Guppington, but I've resolved that problem with rogue (you need to focus on letting him convert coin cards and keep spells in reserve, never using it to clear coin cards). I've built spell setups for every class which are possible to be made every run, before wizard in the list. For wizard, it is an odd one, you could win well with flexible spell combinations while focussing on item builds instead (which need to be heart items, potions and per-hit gauge filling items). My win rate keeps increasing.

I'm looking forward to reaching primal decks as well.

Primal decks are really sucky but it sounds like you have a good grasp on it, best to just plunge in and try them. If you are hitting 98% wins on the others, you might cope better than I did. I have done all the decks now, just trying to find what items I haven't bought yet then do that cosmic inversion achievement.

The third fight is difficult for mainly combo based classes. However it becomes fairly simple once you focus on letting the enemy convert coin cards, and clearing cards to maximise the number which can be converted. This is the case for Rogue and will probably also be for Acrobat. I do not know the default spells for acrobat but it'd also be useful to have or buy the lowest cost heal spell, it really helps as you get individual willpower cards.

As you mentioned, random cards spell is very effective on these classes. When you set up your cards well, the randomise spells will let you hit 20 card combos regularly.

General advice for all classes but especially the agility ones, there are two methods only which need to be set up. You either keep multiples of a card on the board (like when you have two 7s and one 5 and draw a 6, it is better to remove the 5) or set up sequences of numbers, whichever you can and even both when possible. With this you'll be able to start chaining big card streaks. The only class I've played so far which has relied on spells instead was wizard. Even then sometimes I was able to chain streaks (which added to the overall damage along with spells).

I've not saved my spell configurations for past classes but remember them once I select them again. However for most of them I get two each of the attribute spells and one each of the off-attribute ones as I already mentioned (this is not absolute, it turned out with paladin and wizard). For each of them, other than wizard specifically, I found there is a definite best spell build while items can be built flexibly. This made the game relatively easy but can still cost you a run when you are not paying attention. So it is a casual game which can be played near infinitely to me, a casual game which doesn't get tedious with guaranteed wins (a combination I like for when I am tired).

For the primal decks I'd already decided that I'd start off having 3 on-attribute spells and 1 each off attribute, since it is a waste to not have any spell from a particular element. Again this can change if I find a class plays better in another way.

I could probably list all my spell configurations at some point because combined with the card clearing method, you have the ability to win every game without RNG affecting you at all. For me, as mentioned, excessive tiredness and bad play, along with the times I hadn't learnt each deck fully, were the only times I'd lost (and they are few, since I do not move on to new decks immediately and enjoy playing mastered decks I've accumulated many wins).
