Yu-Gi-Oh! TCG - Battles of Legend: Monster Mayhem Review

Battles of Legend: Monster Mayhem, the new Yu-Gi-Oh! TCG set, was released on June 13th, 2025, and brought us excellent cards, including some decent reprints and great support for already existing archetypes.

However, the English version of Battles of Legends: Monster Mayhem was only released in the U.S.A., Canada, and Latin America. Meanwhile, regions like Europe and other countries will have to wait indefinitely to get it. Latin America will also have to wait for the Spanish and Portuguese versions indefinitely.

According to KONAMI, the reason for this delay is an issue affecting the distribution of Starlight Rare cards. Some boxes were shipped with far more of these cards than they should, which altered pull rates, and the only way to fix it was to reship them.

Let's see the best cards from Battles of Legend: Monster Mayhem!

Chibi Cards

Some nostalgic cards were available in Chibi versions in this set:

New Cards

The new "Fabled" support cards are supposed to make this deck playable in the current format. The Fabled Behillmoth, Fabled Gamygyn, and Fabled Realm Resurrection will make it more consistent.

Furthermore, Fabledswarm Leverzebul is a great boss monster. It interacts in a with the opponent in a different way than usual, as it negates the effects of one or more enemy monsters by taking control of them.

This new set also brought more support for "Gem-Knight", an old archetype. This time, however, these new support cards could actually make this deck competitive. Gem-Knight Nepyrim and Gem-Knight Dispersion are excellent and will make this deck a lot more consistent. Gem-Knight Hollowcore, in turn, is a very safe way to interact with the opponent.

As for Gem-Knight Master Diamond Dispersion, it is a great fusion monster, as it lets you access monsters in your graveyard and other fusions straight from your extra deck.

Crowley, the Gifted of Magistus lets you access "invoked" fusions in this archetype thanks to its continuous effect, which lets you treat it as Aleister the Invoker when you use it as fusion material. Furthermore, you can special summon it if you add it to your hand, but not if you draw it.

Zoroa, the Magistus Victorious Verethragna is a new boss monster. Its effect not only negates a monster effect, but also destroys 1 card under the opponent's control at the same time.

Lady's Dragonmaid is the newest fusion monster in this archetype and is supposed to make this deck competitive, as both its effect and summoning condition will make it a lot more consistent. Furthermore, its effect lets you fusion summon something during the standby phase, and this will make this archetype a lot more powerful as well.

Noh-P.U.N.K. Rising Scale is an excellent extender for this archetype, and will also make P.U.N.K. combos a lot better. You can also use it to recycle monsters in "grindy" games.

P.U.N.K. JAM FEVER! is the first xyz monster in this archetype and has exactly what this strategy needed: a monster negate effect to protect it from interactions like Nibiru, the Primal Being.

Enlilgirsu, the Orcust Mekk-Knight is the new boss monster in this archetype and has a very efficient effect - taking control of an enemy monster. You can also banish it from the graveyard to send 1 card on the board to the graveyard.

Galatea-i, the Orcust Automaton is, without a question, the most relevant support card for Orcust because it is a Link-1 monster that lets you set up "1 card combos" in more ways in this deck. With this new card, you'll be able to access both Orcustrated Babel and Orcust Crescendo through the combos.

Reprints

The Dogmatika Maximus reprint is very welcome to players. No meta deck is using it, but it is quite interesting for a few rogue decks and was "bought out" in a few regions, so it has been more expensive lately.

The "Primite" reprint is one of the most relevant reprints in this new set, as many players have been waiting for these cards to get cheaper. However, because of their rarity in this set, they might not get that much cheaper after all.

The Summon Sorceress reprint includes its errata, which makes it more balanced because now it has more restrictions. Among them, it now negates the effects of the monsters you summon with it, and you can only summon monsters in this turn with the same type as them.

This is the first Triple Tactics Talent reprint since it has been limited, which should be enough to make it more accessible money-wise.

The Forbidden Droplet reprint comes at a good time, considering it was getting more expensive in some regions. It might not be thriving in the meta, but it is still interesting.
