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.

Of the 539 cards from 2026 sets that were worth at least 10 (dollars or euro) in week 31 and still priced in week 40, these ten rose the most. Prices are weekly market estimates in each card's own currency.

Patterns

Trafalgar Law twice. Both Law alternate arts from The Azure Sea's Seven are in the top three, and another alternate art from the same set (Zoro) is ninth. Four of the ten are One Piece alternate arts.
Yu-Gi-Oh pairs. The two Maze of Muertos Collector's Rares rose together, and so did the two Elfnote cards — Regina and Lucina, from different sets.
A Commander staple. Arcane Signet is a card played in a huge number of Commander decks; this printing climbed from $49.99 to $88.97.

Most 2026 cards fell over the same ten weeks — 432 of those 539 — as the set reports for Chaos Rising or Adventure on Kami's Island show — which makes these risers stand out all the more.
