Recent public decks
The Warden checks your work
Format legality, color identity, copy limits, and banned cards validated as you build — every flag comes with the reason, not just an ✗.
Combos, surfaced
Commander hubs and Magic card pages show their Commander Spellbook combos beside staples, curve templates, and budget tiers.
Share pages that sell the deck
Every deck gets a fast mobile-friendly page with curve, prices, and a share image that unfurls in Discord — with the commander's art for Magic.
Sample hands
Deal an opening hand in the builder or on any share page — seven cards for Magic, five for One Piece — and mulligan until it reads right.
Tournament finishes
Commander hubs carry recent Top 16 results from Topdeck.gg; One Piece leader pages carry theirs from Limitless.
