Metalfoes Steelen

Metalfoes Steelen debuted as part of the Yu-Gi-Oh! Trading Card Game's Invasions: Vengeance booster set in 2016, later being reprinted as a common in the 2017 Mega-Tin Mega Pack. It belongs to the Metalfoes archetype, a group of Psychic-type monsters characterized by their synergy with Pendulum summoning and their ability to destroy friendly cards to trigger effects and search for support cards. The design features a fusion of mechanical armor and organic forms, fitting the set’s aesthetic of technological advancement and high-octane battle.

The Metalfoes theme was widely praised by the competitive community for its consistent engine and flexible playstyle. By allowing players to destroy their own cards to set Metalfoes spells or traps directly from the deck, the archetype introduced a unique resource management loop. Metalfoes Steelen specifically serves as a Level 3 Normal Pendulum monster, providing the necessary fodder for these destructive effects while contributing to the archetype's tactical framework.
