How do I make a trigger event at the same time happen for every cards?

I hope I word the question correctly, I don't know how to correctly call it.

I have a MoveTo event on a cards family, and basically I want to move them to player's hands.

Here is the event sheet.

It works if I return only one card to player's hand. The problem shows up when I return 2 cards (possibly more than 2 too, but I haven't tested that far). The actions on event 51 only run on one card and not the other. Making one card floating above the player's hand, can't be selected.

How do I make it, so that all the cards returning to player's hands are destroyed and then the game makes a new player hand?

There could be more at play here, but it looks like simply adding "For Each -> Cards" under the Arrived trigger will take care of this issue.

that sounds like a good idea. I think it'll need a bit more than just adding for each, but I'll know for sure when I test it.
