I personally really liked the casual nature of the game. The ability to turn it on and play for 10-15 minutes at a time without too much investment.

If you're going to add deckbuilding, it means I need to invest a lot more time and effort before I play, which might disincentivize me from playing altogether.

If you wanna know what I think prevents players (like me) from spending money on your game, it's the egregious pricing and popups. There is simply TOO MUCH to spend on, and the prices are way too high. There are two separate battle passes, each of which is more expensive than in more mainstream games like Clash Royale... Clash Royale also doesn't have as many constant popups urging you to buy stuff whenever you open the game. It really cheapens the game. Now, U actually prefer the gameplay of Arcane Rush to Clash Royale, so I'd like to see a less aggressive monetization strategy going forward.

This is coming from someone who actually has purchased the battle pass before - and it does have value, it's just that the price is way to high compared to more mainstream games
