Oh no... a card and deck builder ?
I'll still try at some point, but i really don't like card games, it's less tactics and skill and more luck than anything, and i'm an unlucky bastard so i never manage to do good, even when i 100% understand the game.
Still love how the game looks so i'll give it a shot.
I think only some types card games are more luck than tactics. If it's the type that lets you freely adjust your deck (like most TCGs), then luck isn't as big of an influence. If it's the type where you reset your deck and start all over if you lose, luck is a bigger factor, but consistent victory usually hinges on your ability to exploit certain combos (like Slay the Spire). The only games where you're truly at the mercy of luck tend to have very limited capacity of what you can and can't do, like Rock-Paper-Scisssors style battle systems.
Personally, I think anything's fine as long as it doesn't fall into the same pitfall a lot of these card games end up in where there's only like one optimal combo/playstyle and everything else is pretty much hard mode or nonviable. And that shit only works when you have a massive card pool and thorough playtesting and rebalancing, which is why I'm worried.
Something tells me Velminth has been playing Library of Ruina
Library of Ruina's pretty alright. I feel like its stylishness and card variety makes it pretty engaging. It would be hard to emulate its progression system considering that it runs on bulk. You don't get bored as quickly because you're constantly forced to change out your deck loadout as better cards/abilities/stats come in.
If you're wondering how far I've gotten... Two words:
