REDU format ruling
Wild Fire

Nearest-era rulings (Tengu, Sept 2011) — no REDU-specific archive exists.
Card effect (current official text)Pay 500 Life Points. Destroy a face-up "Blaze Accelerator" card you control and destroy all monsters on the field. Then, Special Summon 1 "Wild Fire Token" (Pyro-Type/FIRE/Level 3/ATK 1000/DEF 1000) in Attack Position. Also, you cannot declare an attack this turn.
Rulings
- You cannot activate this card if you do not control a "Blaze Accelerator" card.
- You cannot activate this card if there are no monsters on the field.
- If there are no monsters on the field when "Wild Fire" resolves, you cannot Special Summon any Tokens, but you can declare an attack that turn.
- You cannot activate Wild Fire if you are prevented from Special Summoning monsters, due to an effect like Scapegoat.
- If you activate Wild Fire the effect that you cannot declare an attack affects you, the player, so even a monster that is unaffected by the effects of Spell Cards like Horus the Black Flame Dragon LV6 cannot attack.
- You can activate Royal Oppression in a chain to Wild Fire.
- Blaze Accelerator is destroyed when Wild Fire resolves. If an effect is chained that removes Blaze Accelerator from the field, Wild Fire's effect disappears and you can attack that turn.
