Minefield Eruption
Card effect (current official text)Inflict 1000 damage to your opponent for each face-up "Mine Golem" on your side of the field. After that, destroy all face-up "Mine Golem"(s) on your side of the field.
Rulings
- If you activate "Minefield Eruption", you inflict damage, then send your "Mine Golem"(s) to the GY. So your opponent has missed the timing and cannot activate "Numinous Healer", etc.
- The number of "Mine Golem" cards is considered when "Minefield Eruption" resolves, not when it is activated.
