I'm terrible at act 2. I can't build any viable decks

[Boog]

Please help me out with this one. How should I build my deck? Do I mix deck types? Only focus on 1? What are some good cards I should use? God I'm so confused there's too much choice

Try sticking with one resource type at first. For example, say you have a lot of green wizard and green gem cards, fill the deck with that. Or if you have a lot of bone cards with bone spawners. Or energy cards and energy chargers. There are definitely more complicated deck options, but try to practice with one resource type first, and it gets a bit easier to understand the gameplay.

My initial playthrough I just went full Mox and it worked fine.

If you're going with beasts due to familiarity, robots are better sacrifices than squirrels since they aren't dead draws in later turns. Undead win conditions can make use of all the sacrificing you do early on. I personally found Revenants (3/1 that dies after a turn) more flexible removal than adders (1/1 with death touch).

Full bone deck is fun but I found it challenging to build a deck to beat one of the first two bosses. If you are lucky enough to pull a Tomb Robber you can create skeleton cards for 1 bone, which is borderline broken with beast sacrifice.

Circuits confused me for the longest time especially since the game doesn't explain them unless you pick the robot starter deck. Circuits are best for some 'go infinite' card combos, but unless you're farming foils just use robots as reliable bodies that you can always get out by turn 5.

you can farm foils at magnificus' tower against the training dummy, using this farm you can go to any scrybe's trader and get all the cards you need to build whatever deck you want, just focus on card synergy. i personally prefer the tomb robber and field mice synergy. this is what i use in act 2: Bone heap, Bone lord's horn, pharaoh's pets, tomb robber x2, revenant x2, skeleton x4, meatbot x2 (a low-cost high sacrifice card), mantis god x3, field mice x2, and urayuli x2 (use with tomb robber or meatbot to get this strong boi out) this deck wins every time except when going up against magnificus because he changes your cards effects, but instead i just use skeleton x15, and skelemagi x5 against him since the skeleton cards wont die in one turn thanks to him removing its effects.

if you're having trouble, good old beasts will stomp over everything
it don't matter what deck you pick initially, a couple of beasts packs & you are set
add some free bone energy for sacrifice if needed (meat box / bone box)
you can buy your snek back the from trapper too

I mostly went with blood/bone with a bit of energy. The wizard mechanic just felt awkward and bad; they have no synergy with anything else, along with terrible stats, but the other three mechanics work together pretty well. Going multi-type means that you'll be taking advantage of all of your resources, which makes your plays smoother and more aggressive, or at least that's what I observed.

[Surlyous]

Build flyers + mantis god + that one skeleton which can put skeletons in the hand, have cost 1 bots and rabbit dens in order to smooth our draws, this sweeps every fight except Magnificus who I recommend using a 10 - mix deck and the rest being anything that free cost or 1 cost bots with good stat lines.

There is one rare bone card that comes into play for free and has an activated ability to generate 1 skelly / bone spent, you can use them to sacrifice and when you do you get the bones back creating a cycle that usually is enough to win any fight, if you really want to win easily pair that with ouroboros (You can buy him for 8 foils at leshy's cabin) and then you can ramp ouroboros forever since the method up there is infinite. (You can just hammer ouroboros, making the cycle gives you 3 bones per cycle and you spend 2 bones per ouroboros summon)

There is an auto-complete option at the bottom of the deck building screen that is actually pretty decent at making a balanced deck out of what cards you have available, though there is no guarantee that card balance will suit your personal playstyle. You don't technically have to build hybrid decks, but it is often advantageous to do so as hybrid decks let you use multiple resources if one of them is tapped out. Like regardless what deck type you use, you will still acquire energy as turns pass, and you will acquire bones as creatures die. Those are resources you will end up with regardless of how you are playing, so there's little reason to not include the ability to use them if you have them available. It make both of those decent support decks even if you prefer beasts or mox as your main deck since the resources are essentially provided in a semi-passive manner while beasts require active sacrifice and mox requires active use of mox cards.

Each deck favors a different playstyle though, so which one works best for you is kind of a personal choice unless you want to adapt your playstyle to the strategies others have proven effective instead of developing your own. Each can be powerful in their own ways, and certain combos can be nearly broken, but there's no one "right" way to deck build (although there are some min/maxers out there who have developed decks that are good against most everything). I constantly changed my deck to suit my opponents style, but it was generally a hybrid deck, with my personally favorite supporting deck being the dead cards with a few specific energy based cards tossed in.

I basically focused on a full-time bone deck that leveraged nearly infinite bones from ghost ships, grave robbers, etc. (don't get me started on what's possible with Ouroboros and/or Bone Lord's Horn w/ completed circuit in your deck) to buff bone heaps to the point of absurdity. It got even worse when I added the necromancer, pharaoh's pets, and spore mice, but it essentially wins in the long run every time even if your first matches suffer from poor RNG. Highly recommend as a consistently performing deck
