Beyblade X Deck Sizes: What 3G, 4G, 5G, and 6G Mean
What the 3G/4G/5G/6G deck-size labels mean, why organizers pick one for an event, and how to plan builds around it.
Beyblade X decks are usually described by a number-plus-G label — 3G, 4G, 5G, or 6G. It's a simple idea once you see it in practice, but it trips up new players who assume it refers to a generation of parts rather than the deck itself.
What the numbers mean
The number in 3G/4G/5G/6G is how many separate Beyblade combos — builds — make up the deck you bring to a match. A 3G deck has three builds, a 6G deck has six. That's it. The deck builder on this site uses the same labels for exactly that reason: pick a size, and you get that many build slots to fill in.
Why deck size matters at events
Organizers set the deck size for their event in the rules, because it directly affects match length and how much part variety a player needs. A 3G format keeps matches faster and lowers the part-collection bar for newer players. Larger formats like 5G or 6G give more room to counter-pick between rounds, but take longer to play and ask more of a player's collection.
Deck size is a separate decision from the event's match format — Swiss, round robin, or elimination Top Cut. An organizer might run a 3G Swiss-into-Top-Cut event one week and a 6G round robin the next; the two settings don't depend on each other. See tournament formats explained for how those stages work.
Choosing builds for each size
With fewer slots, each build in a 3G deck has to cover more ground — a common approach is to spread coverage across attack, defense, and stamina rather than stacking three similar builds. With more slots, a 5G or 6G deck has room for a matchup-specific pick or two that a 3G deck can't afford to carry.
Remember that a deck can't reuse the same physical part across two builds — see Standard vs. CX builds for what counts as a part — so a larger deck size also means you need a wider spread of Ratchets and Bits, not just more Blades.
Setting deck size in the tool
Open the deck builder, choose 3G/4G/5G/6G, and the tool adjusts the number of build slots to match. Shrinking the size keeps your existing builds and drops the extras; growing it adds new slots pre-filled with parts that aren't already used elsewhere in the deck, so you're not stuck untangling duplicate parts by hand.
FAQ
Can I mix Standard and CX builds in one deck? Yes — deck size only controls how many build slots you have. Each slot can independently be Standard or CX.
Does deck size affect the tournament's match format? No. Deck size and match format (Swiss, round robin, elimination) are set independently by whoever is organizing the event.
What size should I use for a casual event? There's no universal answer — it depends on how much time you have and how deep your local's collections run. Smaller decks keep things moving; larger decks reward broader collections.
