[BUG] Night Prowler + Hunter's Traps [confirmed]
I dunno if this bug was mentioned earlier in this forum, but I've discovered it when I fought with my Gwen against Banebow.
He layed down 2 Traps and ended his turn. I attacked his Hero with my Gwen using Night Prowler and got a Infernal Gargoyle from his hand. Instantly, I summoned this Gargoyle, but right now, the bug occured: The 2 traps from my enemy didn't activate!
I decided to cast a Puwen next turn and went straight into a Death Trap.
I think traps should activate, even if the ally is originally not in your deck, because there are several ways to get your opponent's cards (Transference, Night Prowler, Gravediggers Cloak, Dimension Ripper).
