Card Tips:Heavymetalfoes Electrumite
- Despite being a "Metalfoes" monster, this card has synergy with any Pendulum-reliant Deck, like "Igknight", "Odd-Eyes", "Magician", "Zefra", "Mythical Beast", "Abyss Actor", etc.
- In a "Zefra" Deck, this card's first effect can quickly add "Zefraath" to the Extra Deck, setting up its Special Summon.
