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.

Barian's Seal (Yu-Gi-Oh (No Set) 38001022). Prices are estimates from TCGPlayer and Cardmarket, not guaranteed values.

When your opponent activates a Spell/Trap Card, or monster effect, while you control a "CXyz" monster or a "Number C" monster with a number between "101" and "107" in its name: Negate the activation, then you can attach 1 monster from either field or GY to 1 Xyz Monster you control. You can banish this card from your GY; Special Summon 2 "Umbral Horror" monsters from your GY. You can only use 1 "Barian's Seal" effect per turn, and only once that turn.
