Because creatures with first strike deal combat damage before creatures without first strike, it’s also possible to have the ability trigger twice in the same combat by your Dragons dealing combat damage to one player at different times. This can also happen if an attacking Dragon you control has double strike.

The triggered ability will trigger once for each player or battle dealt combat damage by Dragons you control, no matter how many Dragons were involved. For example, if you attack a player with three Dragons and a battle that player protects with two Dragons, and they all connect, the ability will trigger twice.

You choose whether to return one of the Dragons that dealt combat damage to the player or battle as the triggered ability is resolving. This doesn’t target any of those Dragons.
