Einmal pro Spielzug

Zitat von Shiny Pika

Kann ich einmal pro Spielzug auch im gegnerischen Spielzug aktivieren oder nur in meinem

Das kommt ganz darauf an, wie der Effekt genau formuliert ist; Bsp.:

NUR im eigenen Spielzug:

• "Chaos Sorcerer": ... Once per turn: You can target 1 face-up monster on the field: banish that target. This card cannot attack during the turn you activate this effect.
• "Alchemic Magician": ... Once per turn, during your End Phase: You can detach 1 Xyz Material from this card and send 1 card from your hand to the Graveyard; choose 1 Spell Card from your Deck, then Set it in your Spell & Trap Card Zone.
• "Blaze Fenix, the Burning Bombardment Bird": Once per turn, during your Main Phase: You can inflict 300 damage to your opponent for each card on the field...

AUCH im gegn. Spielzug:

• "Legendary Six Samurai - Shi En": Once per turn, when your opponent activates a Spell/Trap Card, you can negate its activation and destroy it...
• "Abyss Dweller": ... Once per turn, during either player's turn: You can detach 1 Xyz Material from this card; any card effects that activate in your opponent's Graveyard cannot be activated this turn.
