Provenance

Where it came from

Mathmech Addition was originally released in the 2020 core set Ignition Assault as part of the Cyberse-type archetype designed by Konami. The archetype centers on mathematical terminology and geometry-themed aesthetics, with the monsters appearing as digitized, angular entities. The design philosophy behind the Mathmech series emphasizes swift special summoning and aggressive stat manipulation, encouraging players to quickly swarm the field to execute link or synchro summons.

The reprint featured in Ghosts From the Past: The 2nd Haunting, released in 2022, provided this card in an Ultra Rare foil treatment. This set was designed as an all-foil supplemental product intended to reprint highly sought-after cards from various archetypes alongside new support. While the card itself remains a functional piece of competitive Yu-Gi-Oh! strategy, this specific iteration is valued by collectors for its distinct, high-shine finish that distinguishes it from the original common print.
