Those cards are for FAMILIAR SYSTEM.
Monster collection is a completely different system that has no connection with familiars.
And nexon has disabled the Familiar system due to many problems that occurred after launch. Also you can relog to turn your character back to normal after trying to use a card
Since the farm system is really old and receives updates fewer times than it should, I suggest that Nexon may add a preset system to change farm layouts faster, similar to the Legion preset system. This way we could change between focused decoration layouts and waru production faster, or any other layout you may be pleased.
Because we don't give nexon enought money to make viable to invest in hiring a translator or physically building a server in south america. BMS was shut down due to low revenues, and it will be unlikely to ever be a new server around
