Rulings
- "Battling" requires this card to be involved in Damage Calculation (If this card's attack is negated, the ② effect can't activate).
- If multiple "Gladiator Beast" effects are activated at the end of the Battle Phase, they don’t go on the same Chain (they each activate, one after another, each on their own Chain).
