the chess board and 1v1 is battle chess from the 80's with an added layer of making the 1v1 more of a TCG style battle.
No issues with this. I like it a lot. Just trying to be honest of how it will work.
Your definition of "combo of chess'ish/ hearthstone'ish/ poker'ish"
is "Battle chess clone / TCG combat system / MTG 6th edition stack rules for bluffing strategy"
Like I said I love the idea but from a game designer view this is what it is.
(remember I have been doing table top, card game, board game, video game design for 25+ years so I just clarifying in my own head)
