Techs

With the recent support wave, most of the possible techs this deck can run have been pushed out of viability due to deck space.

Then there's the extra deck, which has always been tight but now reaches new limits.

• Main Deck
• Extra Deck

Engines

As with the generic techs, there just isn't much deck space for external engines anymore.

• Kashtira
• Machina
• Symphonic

cores too

DISCLAIMER: All combos listed here can be modified to better suit your current matchup or the contents of your hand. Freestyling based on the contents of your hand is almost always better than using a set line, as it allows you to play around or through interruptions more often, but it's not the easiest thing to pick up, so mess around with these to help yourself learn until you get used to the deck.

As these are mainly here to provide inspiration and help you get more acquainted with what the deck can do, only a fraction of the possibilities are covered - a fully complete combo sheet would be absolutely enormous and also literally 3-dimensional.

Huge shoutout to Yukinon for working on compiling a combo spreadsheet for everyone while this site was under construction.

There's several differences between MD and TCG - the legality of Maxx, the best-of-1 format, the different banlist (mainly Baronne), and the lack of the new support.

Due in large part to the last point, most of the information is this guide is not transferable; the deck instead plays like it did in 2023. There's a more specific Master Duel guide written by Quariongandrax that you can check out.

The cockroach necessitates the maindecking of outs, as it's the only handtrap that's guaranteed to end your turn unless you have an answer to it; the Speedroid engine does not trade well into it at all, taking at least 2-3 Special Summons to field 1 interaction.

Best-of-1 incentivizes you to maindeck things that you wouldn't normally, such as going 2nd cards like Evenly or Duster, so that you don't automatically lose to random things you find on ladder. It also accentuates the deck's inherent randomness, so sometimes you'll just get bad RNG and not have a game 2 or 3 to salvage things.

One of the other problems with the deck is also emphasized - without the new support, it still feels like a 2021 deck, and that's generally just not going to cut it in 2025.

Overall, a sample decklist doesn't look too far removed from an old TCG list. Larger deck sizes are somewhat discouraged in order to more consistently see Maxx counters, but going over 40 is still fine. As with everything else, feel free to tweak ratios and techs as you experiment with the deck and become more used to your own playstyle.

As always, feel free to ask in the Discord server if you have any questions.

Most of the archetypal cards can be obtained from the secret pack; craft a Terrortop or CarTurbo to unlock this if you don't already have it available. However, you'll still need to craft a number of cards for the core as Konami never bothered to update the secret pack even though Beyond Speed was one of the first selection packs added to the game.

Wynn vs Scratch vs Small World

This gets asked a lot, and the simple answer is that Small World is superior to the other two, but you don't really need any of the three at lower deck sizes since the deck is already extremely consistent.

• Note that you DO need at least 1 copy of Scratch in order to open up a large number of combo lines.
• Small World is especially nice to have if you play a variety of Attributes that makes Wynn worse, like a Crossout Designator handtrap spread, but practically all of the available paths get filled naturally regardless of your deck's composition. It not going -2 for cost and being able to search any monster off of any other monster, including searching or using handtraps, are very large points in its favor. Banishing is worse than discarding, but situations where the distinction actually matters are quite few and far between.

If you can't use Small World for whatever reason, the best option is often to simply not run any of the searchers because they trade badly into disruption and you'll often wish they were simply a generic extender instead. If Wynn or Scratch gets negated, you're left with 3 cards in hand; if you can still play at that point, then you could have been running a generic extender instead and it would have helped just as much, if not more since they're better to see when going 2nd*. Additionally, there's a very narrow range or "good" discards: Piper, Daiko, and Dice are the only things you actually want to have in the GY, unless you opened Yoyo or Recovery. Discarding a Marble or Taketomborg for cost with no idea whether you'll recoup that loss is not a great idea. If you are dead set on running one or the other, the optimal choice depends on the rest of your deck:

• Wynn is better to run if you're just running some WIND generics like Droll & Lock Bird or extenders like Wandering Gryphon Rider, since she's able to search and/or discard them in addition to your Speedroid monsters.
• Scratch is better if you play an incredibly pure build with no generics, as it will have more available discards in the form of Dupligate compared to Wynn (being able to discard Wheel is essentially a non-point, as doing so is practically never good unless you drew 2+ copies).

A mix of these two is also an option; some run 2 Wynn + 1 Scratch due to the latter's searchability off Cork.

* The same point can be applied to Wheel; however, Wheel can be and is primarily used as an extender for after you get interrupted or have already ensured you have a setup, whereas Wynn and Scratch are far better off being used as starters and as such are more vulnerable.

1 vs 2 Copies of Red-Eyed Dice

Routing lines with Dice in hand is quite easy to do with little practice and practically always gets you the same endboard as you could have made without seeing Dice at the cost of losing that extra card in hand, so running a second "in order to always have 1 in deck" is incorrect. Additionally, here's some math:

• With 1 copy of Dice in a 40 card deck, you will see it in 12.5% of games; with 2, you will see a Dice in 23.72% of games.
• The odds of having a game where you roll exactly a 2 off Wheel are slightly higher than 5.62%, as you only open Wheel in 33.76% of games but there are times where you want to search it off Cork, and resolving multiple is a fairly rare occurrence.

This means that by putting a second copy of Dice in your deck, you are taking a 11.22% decrease in the deck's overall power to gain around a 5.62% boost to Wheel's consistency, which itself barely matters since the deck is already super consistent. The majority of the time, rolling a 2 off Wheel will not immediately lose you the game, so this is overall not a great trade.

The one benefit to running 2 copies of Dice is that it can make combo lines slightly simpler, but this isn't necessary unless you're just learning the deck.

Deck Size Theory and Ratios

Contrary to popular belief, if you scale up your ratios for starters/extenders along with your deck size, you can go over 40 cards without any loss in consistency - even getting a boost in some areas.

If you have enough cards to be able to scale up (this deck does), the only real drawback to going over 40 is that you see specific names less (which can be important post-siding or with power cards like Crossout Designator that you always want to see, but also reduces your chances of drawing bricks).

If you do run over 45 cards, it's generally recommended to run one of the searchers mentioned in the previous section, as the deck lacks other starters that don't use the Normal Summon and running 9+ NS is definitely too much.

Overall, it's a calculation of tradeoffs; do you value overall consistency and flexibility more, or being able to see specific power cards more?

In the end, like a lot of other things in the deck, it mostly comes down to personal preference as many people have seen success running 45 or more. Here's a calculator if you want to do some math yourself; messing around with it can give you some new insights.

Additionally, here's some basic numbers to illustrate the point:
