work? For example, if my opponents activates compulsary evacuation device, or trap hole does junk destroyers affect activate?
Also, does this also apply for Trishual?
Yes it does I'll explain it a bit. Junk destroyer, trishula and even black rose dragons effects are ignition effects which means they activate when summoned. If I use any of the mentioned cards on these synchros there effects activate, because none of those card's specifically negate there effect's. It's pretty much chaining an mst to a monster reborn and destroying it scenario you didn't stop the effect you just destroy the spell same goes with trap. Hope I helped.
