What does a card with "X in its text" refer to?
- Answer
It refers to a card that contains the specified text or icon in its name, traits, effects, inherited effects, ⟨Rule⟩, digivolution requirements, DNA digivolution, DigiXros requirements, burst digivolve, App Fusion, Link, or Assembly requirements.
For example, a card with [Knightmon] in its text would include cards with the name [DarkKnightmon] and cards with the text [Knightmon] in their effects.

- Question
Can I use this card's [On Play] [When Digivolving] effect to give "[Start of Your Main Phase] This Digimon attacks" to a Digimon that isn't affected by effects?
- Answer
You can give that effect to such Digimon, but if the Digimon isn't affected by effects upon the trigger timing, the gained effect won't trigger.

- Question
I chose my opponent's BT16-048 [TyrantKabuterimon] for this card's [On Play] [When Digivolving] effect.
If BT16-048 [TyrantKabuterimon] then attacks and is suspended at the start of the main phase, does its gained <Collision> activate?Sep. 5, 2025 Updated
- Answer
No, <Collision> doesn't activate.
As soon as BT16-048 [TyrantKabuterimon] suspends, its [All Turns] effect prevents it from being affected by your effects, and <Collision> doesn't activate.
