Ethereum card game circa 2018

I remember I used to play this ethereum card game which was based around monsters. You had the ability to fight other players and you would get rewards that could go towards unlocking new cards. These cards also had a secondary marketplace for buying and selling using ethereum. Does anyone else remember the name of it? I cant find any mentions of it but I have the account address I interacted with. Here's the account on ether scan. I would interact with in order to battle other players. Anyone know if this game is still a thing?
