Can I build a deck together with friends on TCGSwap?

Yes. Every deck on TCGSwap has a Collaboration Space. You can invite up to 5 friends; they can suggest card changes, discuss ideas, and playtest proposals. You review and apply suggestions before anything changes in your deck.

How does deck collaboration work?

It works like a pull request for your deck. Collaborators open the deck editor, make their proposed changes, and submit a suggestion with a note. You get notified, open the comparison view to see exactly what they changed, and choose to apply all, cherry-pick individual cards, or decline. Nothing changes in your deck until you approve it.

Can collaborators chat and discuss the deck?

Yes. The Collaboration Space has a shared group discussion thread for the whole deck, plus a per-suggestion Q&A thread for each proposal. You can @mention teammates and link specific cards inline.

Is collaborative deck building free?

Yes, collaboration is free for all TCGSwap users during beta. You can invite up to 5 collaborators per deck.

Does TCGSwap work for MTG, Pokémon, Yu-Gi-Oh and One Piece collaboration?

Yes. The Collaboration Space supports all four games — Magic: The Gathering, Pokémon TCG, Yu-Gi-Oh and One Piece. Format validation and card prices are included for each game.

''"BULLauncher" is a support machine specializing in bombardment and daytime combat that not only has the constantly refined "Coc-OS" and "BFS Armor", but it also has 3 "Foil-Packers" installed within it under orders of "Madera" after repeated trial and error. By installing a "Beef-Rifle" or other armaments, it can be used as medium- and long-range support for the "Steam Knights" and their operations. Also, "BULLauncher" can be combined with "WINGear", which specializes in high-speed aerial combat, and "BOARms", which specializes in melee and assault combat, to cause the high-calorie "Steam Jushin - BW" to descend upon this world.''
