Looks really nice, specially the main menu UI, also I like how it is being made with mods in mind, modding is love, modding is life, ok now for feedback
The game is MGT without lands which makes it a better game already, I just think it is weird to have mechs in the wizard deck
-Use more Keywords, example: Mech Bruiser "When this minion enters the battlefield, deal 2 damage to any target -> Mech Bruiser: "Summon: deal 2 (icon for damage type) to any target", there are many more things that can become keywords
-On the first zone the game is very fun, but starts getting very unbalanced later on, you can get killed by burn damage very easily if the enemy has a burn deck, and you can get some very east wins if the enemy only has high cost cards and is unnable to do anything in the first 2 turns
-The idea of creating cards is very nice, but is extremely easy to exploit and I don't think it is possible to make the game balanced if this stays part of the core gameplay
-I really dislike the luck events, I think the game would be better if luck events and the luck stat were both removed
-The wizard ability is useless, In roguelite games like these you should never skip a combat, a better skill would be something like Clairvoyance: allows you to see the enemy deck before battle
Overall very good and has a lot of potential
