Official clarifications published for this card.
I used an effect to use an Option card with an original use cost of 2 or more without paying the cost. At such times, does this card's "when you use an Option card with a use cost of 2 or more" effect trigger?
Yes, it triggers.
21 November 2025
Does the "when you use an Option card" effect trigger if an Option card's effect activates by a method other than using the card?
No, it doesn't trigger. If an Option card's effect activates without using it, such as activation by a [Security] effect or <Delay>, the "when you use an Option card" effect doesn't trigger.
21 November 2025
If the "when you use an Option card" effect triggers, what is the timing when it can activate?
It can be activated after activating the used Option card's [Main] effect.
21 November 2025
An Option card's use cost is 1 or less when used from the hand due to an effect such as BT2-099 [Glorious Burst] or BT8-097 [Crimson Blaze]'s 1st effect. When such a card is used, does this card's "when you use an Option card with a use cost of 2 or more" effect trigger?
No, it doesn't trigger. If a card's cost itself is reduced when it's used from the hand, it's considered to be using an Option card with a use cost after the reduction is applied. Therefore, the "when you use an Option card with a use cost of 2 or more" effect doesn't trigger.
