Battles of Legend: Monster Mayhem Set Guide
A 177-card set with no card below Ultra Rare, most of it reprints. Its 43 new cards include small groups for Fabled, Jurrac, Gem-Knight, Nekroz, Dragonmaid, P.U.N.K. and Orcust, and the Starlight Rare Blue-Eyes White Dragon is the chase.
Overview
Battles of Legend: Monster Mayhem released August 28, 2025, with 177 cards under the BLMM set code. Every card with a listed rarity is an Ultra Rare, Secret Rare or Starlight Rare, so the set has no Commons, Rares or Super Rares.
Most of it is reprints. 134 of the 177 cards were first released in earlier sets, and the 43 new cards run from BLMM-EN011 to BLMM-EN053, in small groups for themes such as Fabled, Jurrac, Gem-Knight and Nekroz, which the set also reprints older cards for.
The first ten cards, BLMM-EN001 to BLMM-EN010, are older cards reprinted at Secret Rare and Starlight Rare, starting with Blue-Eyes White Dragon. Its Starlight Rare was the most valuable printing in the set on September 30, 2026, at $163.95.
Cards and rarities
Battles of Legend: Monster Mayhem has 177 set codes, each starting BLMM-EN and printed under the artwork on the right. Where a card comes at more than one rarity, every version shares its code, so the table counts set codes at each rarity and a code printed at two rarities is counted twice.
The catalog does not list a rarity for 22 of the 177 set codes yet, all of them new cards between BLMM-EN012 and BLMM-EN048. Every Starlight Rare shares its set code with an Ultra Rare or Secret Rare printing of the same card, which is why the counts add up to more than the 155 set codes with a listed rarity. Set completion in TurnZero HQ counts the distinct set codes you own against the set's total, so a card printed at two rarities counts once, with an every-rarity count beside it for collectors chasing each version.

New cards
Most of the 43 new cards come in groups of two to four for one theme. The last five, for Dragonmaid, P.U.N.K. and Orcust, are the new cards printed at Ultra Rare and Starlight Rare, and each of those themes gets a block of reprints later in the set.
Lady's Dragonmaid
BLMM-EN049
A Fusion of 2 Dragonmaid monsters with the same Attribute but different Levels, Special Summoned by banishing one from your field and one from your GY. It Special Summons a Level 4 or lower Dragonmaid from your Deck, and in the Standby Phase it can Fusion Summon a Dragon Fusion Monster.

Reprints worth knowing
Most reprints are Ultra Rares, and a few are general cards rather than theme support. Necroquip Princess and Herald of Orange Light also come as Starlight Rares.

The chase card: Blue-Eyes White Dragon
Monster Mayhem's chase card is the Starlight Rare Blue-Eyes White Dragon, at $163.95 on September 30, 2026. That was more than twice the next printing, the Starlight Rare Galatea-I, the Orcust Automaton at $75.43.
Blue-Eyes White Dragon is a Level 8 LIGHT Dragon Normal Monster with 3000 ATK and 2500 DEF, first released in 2002 and reprinted many times since. In Monster Mayhem it is BLMM-EN001, the first of the ten older cards reprinted at Secret Rare and Starlight Rare.
The Secret Rare of the same card was $12.66, so the Starlight Rare cost about 13 times as much.

Playing it
Four Monster Mayhem cards are on the Forbidden & Limited List as of October 1, 2026. King of the Feral Imps is Forbidden, and Gem-Knight Master Diamond, Summon Sorceress and Triple Tactics Talent are Limited.
The reprints are grouped by theme. BLMM-EN054 to EN069 are sixteen Dragonmaid cards, EN070 to EN081 are twelve P.U.N.K. cards, and EN082 to EN098 are Orcust and World Legacy cards with the Link Monsters around them, so the new cards for those three themes sit in the same set as the older cards they work with. Later reprints cover Gem-Knight, Nekroz, Jurrac, Heraldic Beast, the Dragon Rulers and True Draco.
If you are buying singles to play, the reprints are cheap below Starlight Rare. 113 of the 134 reprinted cards were under $1 at their Ultra Rare or Secret Rare printing on September 30, 2026.
