Evenly Matched

Per-phrase breakdown

• At the end of the Battle Phase, if your opponent controls more cards than you do: You can make your opponent banish cards from their field face-down so they control the same number of cards as you do. (Effect)
• If you control no cards, you can activate this card from your hand. (Condition)

Judge-facing facts

• Trap Card.
• Can be activated at the end of the Battle Phase (End Step) of either player's turn.
• Activating this card from the hand when you control no cards is an activation condition, not an effect.
• You must count Evenly Matched itself when determining the number of cards you control at activation. If you activate it from your hand while controlling no other cards, you control 1 card.
• The effect forces the opponent player to banish cards; it does not affect monsters. Monsters unaffected by Trap effects will still be banished face-down.
• Tokens cannot be banished face-down. If the opponent controls only Tokens, this card cannot be activated.

Card-specific notes from database

• (YGOResources) If you control no cards and your opponent controls exactly 1 card, you cannot activate Evenly Matched from your hand, because you will control 1 card (Evenly Matched) upon activation, meaning your opponent does not control more cards than you.
• (YGOResources) If your opponent controls Tokens and other cards, they must choose to banish the non-Token cards face-down.
• (YGOResources) If you control a card that prevents the opponent from banishing (e.g., Chaos Hunter), you cannot activate Evenly Matched. If your opponent controls Chaos Hunter, you can still activate it.
• (Konami neuron) Monsters that 'cannot be banished by card effects' (e.g., Metaphys Executor) can be banished by Evenly Matched, as the banishing is performed by the player.
• (Konami neuron) If a monster that is banished when it leaves the field (e.g., Floowandereeze x Robina, Plaguespreader Zombie) is chosen to be banished by Evenly Matched, it is banished face-up instead.
• (Konami neuron) Transaction Rollback cannot copy Evenly Matched except at the end of the Battle Phase, because the activation condition must be met.
