"U.A. Penalty Box":

OCG Rulings

The activation of only the card "U.A. Penalty Box" can be performed at any time, except during the Damage Step. Furthermore, if the effect "At the start of the Damage Step, if your "U.A." monster battles an opponent's monster: You can banish that opponent's monster until your opponent's 2nd End Phase" is activated in the same Chain Link, the card "U.A. Penalty Box" can be activated at the start of the Damage Step.^[1]

The effect "At the start of the Damage Step, if your "U.A." monster battles an opponent's monster: You can banish that opponent's monster until your opponent's 2nd End Phase" makes a Chain Link. (It does not target. Also, returning a monster to the field that was banished by this effect does not make a Chain Link.)^[1]

If an opponent's monster is banished by the effect "You can banish that opponent's monster until your opponent's 2nd End Phase", the Damage Step ends with damage calculation.^[1]

The effect "You can banish this card from your Graveyard; add 1 "U.A." Spell Card from your Deck to your hand" is activated in the Graveyard and makes a Chain Link. (It does not target. "U.A. Penalty Box" itself is banished from the Graveyard itself as a cost when this effect is activated. Also, this effect cannot be activated during the Damage Step.)^[1]

After a monster is banished by the effect of "U.A. Penalty Box", even if "Mystical Space Typhoon" is activated and "U.A. Penalty Box" is destroyed, the monster banished by the effect of "U.A. Penalty Box" will still return to the field during the opponent's second End Phase after activation.^[2]

Even if your "U.A." monster attacks an opponent's face-down Defense Position monster, the effect of "U.A. Penalty Box" can be activated. In that case, the opponent's monster is banished face-down, and it will return to the field during your opponent's second End Phase in face-down Defense Position.^[3]

After a monster is banished by the effect of "U.A. Penalty Box", even if "Royal Decree" is activated, the monster banished by the effect of "U.A. Penalty Box" will still return to the field during the opponent's second End Phase after activation.^[4]

If the effect of "U.A. Penalty Box" is activated during your opponent's turn, the End Phase of that turn counts as the first End Phase. Therefore, the second End Phase after activation will be the End Phase of your opponent's following turn.^[5]
