I'm not sure if this was something strange on the Mobile App or I'm missing a rule somewhere that causes this to happen this way.
Stuntman had Moving Target, Hidden Mine and Lance-Flammes in play when Set is going to deal each hero target 1 lightning damage. I chose Stuntman to get hit first which Triggers Moving Target and Hidden Mine. The game asks which one you want to do first, so I picked the Hidden Mine, thinking I can drop some other Ennead health then Lance-Flammes to take out the now low health targets. The Hidden Mine incap's Set and then the game moved on. Shu heals, then its Luminary's turn. I went back and tried it the other way too. Used Moving Traget to Lance-Flammes, Lance-Flammes incaps Set the game moves on Hidden Mines doesn't set off.
What would stop me from getting both effects?
