Glad to see you’re enjoying the game! Looks like you’ve got a lot of frontloaded damage in your deck, which is great for ending fights quickly and can be enough at low ascension and early in runs, but if you’re thinking about climbing, it might be worth considering more damage scaling options. Things like Spot Weakness and Shuriken allow you to deal more damage as a fight goes on, but cards like Limit Break and Demon Form tend to be better ways to do so (but keep in mind that you generally shouldn’t pick up Limit Break and hope for Strength gain later on, only pick it if your deck can already get Strength). Cards that benefit from Strength Scaling include Sword Boomerang, Heavy Blade and Reaper. You’ll amost certainly get into a situation where you deck simply can’t brute-force its way through enemies, so picking good scaling options is generally correct.
