Explained
Set it from your hand as a Spell. If it's destroyed while Set on your opponent's turn, it Special Summons itself. When Special Summoned on your opponent's turn, it revives an "Artifact" from your GY, then you can only Special Summon Artifacts until the end of the next turn.
It can't be used in Advanced Format. It's Forbidden in the TCG.
- Forgetting the Artifact-only summon lock lasts until the end of the next turn.
