Heya,
during Christmas holidays I've ported a lot of stuff to the new engine. I've also had a quite funny first multiplayer match with two friends and the three of us made it until wave 50 (then the simulation crashed :-)).
Besides porting stuff, I've also implemented a new legendary potion, that should enable some interesting strategies.
Update: I've adjusted the lore of the card. Thanks Jhoi Ashleigh for your suggestions!
