Plugin is fun but there's no way to directly contact the developer.
A lot of battlecards don't do anything at all other than following you, sometimes they leave parmenent blocks or texts in the air.
There are bugs here and there.

Would be good to issue them without using github to have a direct contact with the Dev.

I use paper 1.20.1

Great.
Sadly no possibility to contact you :/
Please add a Card Storage / Card Backpack / Card Inventory to store collected cards via mysql for cross server support (storaging) and that his storage can be upgraded to unlimited (tier1, tier2, ... ) everything defined in config. That would make it perfect because with tons of cards you need tons of chest and thats to complicated and a automatic sorting system would be great too. That would be very awesome.

I'm sorry, I don't speak English. I translated this message through a neural network. This is a wonderful plugin and fulfilled all my desires on my anarchic hardcore server. in the future, I will translate and arrange all the cards in the style of "artifacts" and they will fall out of the mobs when "ejected"! This is excellent! From Russia with love.

OMG! this battle card plugin works! I will like this plugin! thank you! But I have a question! How can I get a card? mob drop or only command? And how can I using card workbench? I want this information, but there's no information on video...TT

OMG! this battle card plugin works! I will like this plugin! thank you! have a nice day!

I want to playing this plugin, but it didn't work. I download this plugin and KotlinMC, insert my server's plugin folder but there's error. how can I fix it? My version is 1.20.2

First to download and install, very good, need a written guide on how to level up, and combine, and add items to cards.
