Q1: When placing cards from my opponent's trash at the bottom of their deck with this card’s When Digivolving effect, who gets to decide the order of the cards?
The player who controls this card decides.
Q2: Does this card’s When Digivolving effect let me place Digi-Egg cards from my opponent's trash at the bottom of their deck?
Digi-Egg cards in your opponent’s trash can be chosen as part of the effect, but they’re returned to the bottom of your opponent’s Digi-Egg deck instead of their normal deck.
Q3: If there are 2 cards with Mega in their traits in this Digimon’s digivolution cards, do I get to place 20 cards from my opponent’s trash at the bottom of their deck with this card's When Digivolving effect?
No. Even if you have multiple cards with Mega in their traits, this effect will only place 10 cards from your opponent's trash at the bottom of their deck.
Q4: If my opponent has 9 or fewer cards in their trash, does this card’s When Digivolving effect still activate?
Yes, it does. Place as many cards as you can at the bottom of your opponent’s deck.
Q5: Can I choose not to activate this card’s Start of Your Turn effect to avoid trashing any cards?
No, you can't. You must activate this effect at the start of your turn.
Q6: Does this card’s Start of Your Turn effect activate even when my opponent’s security stack is empty?
Yes, it does. While there are no cards in your opponent’s security stack to trash, you still perform the part of the effect that reads, “Trash the top card of this Digimon.”
Q7: Does this card's Start of Your Turn effect activate when this card has no digivolution cards?
No. When there are no digivolution cards, you can't perform "trash the top card of this Digimon," so it doesn't activate.
Q8: My turn starts when I have this card with BT9-083 Omnimon: Merciful Mode as its top digivolution card. If I use this card's Start of Your Turn effect to trash this card, then activate the Start of Your Turn effect on the BT9-083 Omnimon: Merciful Mode that was a digivolution card, can I trash a total of 2 cards from my opponent's security stack?
No. The Start of Your Turn effect on the BT9-083 Omnimon: Merciful Mode that was a digivolution card isn't yet in a state where it can activate at the start of your turn, therefore it doesn't trigger.
