Multiple copies of Decoy Trap don't trigger simultaneously

[BP Holy Punisher]

I had 2 Decoy Traps placed on board and I had also 3 allies, Aldon, CoI and Bobcat. The opponent played Tidal Wave and only the first Decoy Trap triggered and saved Aldon. Why was the second Decoy Trap not triggered at the same time? Is this as it is supposed to be or it is a bug?
As I have seen, many Decoy traps can be triggered at the same turn but as a consequence of a separate damage source.

Heya,

That is a bug. Assuming you have multiple allies that can be protected from damage by decoy trap, then each ally should be gaining benefit from a Decoy Trap when it takes damage. The Standard Resolution Order (SRO) would determine which allies get protected by decoy traps based on the order they were played.

Hope that helps

As far as I can tell, there is an unwritten rule codified into the game that only one trap can go off per action. This is why multiple Net Traps don't go off when you summon an ally. But if a trap responds to damage, then I suppose you might expect an action that damaged multiple targets to have multple traps go off? Indeed, that is how Mojumbo interpreted it.

However, we can't make such a ruling without discussing with Kyle. Maybe the unwritten rule just needs to be written down somewhere and then the current behaviour is correct.
