Decoy Trap vs. Death Trap
Built a Hunter deck to try some thing out and encountered this against the AI Gwen. (Why on the Test server do Human Heroes play against Human AIs while the AI is Shadow on the Live one?) I played a Decoy Trap then dropped an Ally.
AI Gwen had a Death Trap out, it tried to kill my ally but Decoy Trap activated and neutralized Death Trap letting the Ally get played.
Is this intentional? Death Trap doesn't say it does damage, it just kills. Decoy Trap says it reduces damage to 0.
