Brilliant. And I love that it uses the Spanish deck.
The burning mechanics is important, as you explained in the dev note (https://jvolonte.itch.io/pegote/devlog/1556429/what-is-wrong-with-pegote), and yet it's not entirely clear. I seldom felt that I had really bad cards that I wished to burn, but this is probably just a by-product of my opponents not being very strong in the demo; and yet, if they were stronger the cards acquired from them would be stronger anyway… I'm afraid in most cases the real point of the fire is the collateral effect of stickers like Explosion. But if you placed such a sticker on your card and you kept it's because it's a winning card and I won't be thrilled at burning it…
Hm, OK, the more I talk about this and the deeper it looks! Well done.
