Interactions
If Debris Dragon revives Lonefire Blossom, can Lonefire still resolve its effect?✓
Lonefire is Special Summoned by Debris.
You may activate Lonefire and pay its cost, but the effect resolves negated due to Debris Dragon.
If Black Rose Dragon is Synchro Summoned with Dandylion and then destroys my Dupe Frogs, do the Dupe Frogs miss timing?✓
Debris Dragon and Dandylion are used to Summon Black Rose Dragon and its effect activates with Dandylion on the chain.
Yes. Dandylion must be Chain Link 1 and Black Rose Dragon is Chain Link 2, so the destruction is not the last thing to happen. Dupe Frogs destroyed by Black Rose will miss timing.
