Q1: This card has 3 different cards in its App Fusion requirements. What combinations are possible for App Fusion?
App Fusion is possible with the following combinations. <ul><li>Gatchmon with Navimon link card<li>Gatchmon with Tweetmon link card<li>Navimon with Gatchmon link card<li>Navimon with Tweetmon link card<li>Tweetmon with Gatchmon link card<li>Tweetmon with Navimon link card</ul>
Q2: I link [[BT21-018|BT21-018 DoGatchmon]] with this card and use its effect to attack. Can I then use the effect on the linked [[BT21-018|BT21-018 DoGatchmon]] to attack?
No, you can't use the effect on the linked [[BT21-018|BT21-018 DoGatchmon]] to attack. A new attack declaration can't be made during an attack. In this case, this card's Your Turn effect and [[BT21-018|BT21-018 DoGatchmon]]'s {{WhenLinking}} effect trigger simultaneously, and this card's Your Turn effect is used to attack. [[BT21-018|BT21-018 DoGatchmon]]'s {{WhenLinking}} effect can be activated before the counter timing, but because you can't declare another attack during an attack, you won't be able to attack using the linked [[BT21-018|BT21-018 DoGatchmon]]'s {{WhenLinking}} effect, even if you activate it.
