After playing it a bit I understood the concept and was able to win one against the first AI. I enjoyed my time with it though once I understood that the mechanics

The player starting combines don't have a lot of immediate attack power, so enemy cards like "Tinkerer" are very dangerous to you and snowball the match very quickly. Also on rounds where I didn't start with the ingredients for the rodente, I felt like I would be out of any options right as the AI was hitting it's stride and getting a big 5/4 robotinger on the field.
On the 2nd AI opponent that spawns the flower card every turn, I could not manage to chip away enough health to realistically beat them before their big cards came onto the field, for which I had no answer.
Also biggest feedback point of all, LEFT CLICKING to clear the cauldron needs a confirm if it's going to waste the player material. This is what ultimately made me stop attempting to beat opponent #2 as an accidental misclick basically doomed me

I played a few more rounds with the knowledge that the resource bar on top was mine to spend, it did make it a bit easier to get some higher level red monsters out on the field. Still, I think if you don't get an early rodente on the field for card draw, the player is resource starved.
Also I think there may be a bug related to the Lost Viking card's effect trigger. I've seen it twice now that the entire game stalls out when trying to trigger the effect after the Lost Viking dies.
Anyway good game, the art is great especially
