Dice, sleeves, or a mat
A seven-die RPG set rolls a check. Sleeves keep a constructed deck identical at a tournament table. A playmat is the rectangle the cards sit on. They are different objects. Pack the one the table actually uses.
What each object does
| Object | Job | Rule that names it |
|---|---|---|
| Polyhedral set | Resolve an uncertain action | D&D Basic Rules, Game Dice: d4, d6, d8, d10, d12, d20. Uncertain actions use a d20. |
| Card sleeves | Protect a constructed deck so every card matches | Magic Tournament Rules §3.11. Play! Pokémon TCG Handbook §2.2 wants the whole card enclosed. |
| Playmat | A play surface for the sleeved deck | Those sleeve paragraphs do not name a mat. It is the cloth, not the roll. |
Sleeves do not roll a check. Dice do not sleeve a double-faced card. If you are packing a bag for D&D, start with the set. If you are packing for a Pokémon or Magic event, start with identical sleeves. A playmat is the third object, useful once the deck is sleeved and you want a clean rectangle on a shop table.
Opaque sleeves are required for double-faced Magic cards under MTR §3.11. Play! Pokémon wants the whole card enclosed, matching color, design, size, and texture, with a solid-color edge. Opaque backs are strongly recommended there. Those are tournament sentences. A kitchen-table game can still use the same objects. It does not have to.
A seven-piece bag if the table rolls. Get this. Matching sleeves if the event sleeves. Get this. A mat only if elbows meet. Get this.
The longer lecture, with the WPN and Play! Pokémon links, is Dice vs sleeves. Gear cards live on Shop. Local shops are a later directory if you want a table tonight, not the first stop on this page.
A dice tray is a fourth object people mix in. It catches a roll so the d20 does not hit a glass. The Basic Rules do not require a tray. Tournament sleeve rules do not require a tray. Bring one if the table is crowded. Leave it if you are only sleeved for a constructed event and the dice stay in the bag.
