Tomado del ruling oficial de la data base en japon:
There are no Spell/Trap Cards on my field, and my Topologic Trisbaena is in the Extra Monster Zone. In this situation, if I activate the effect of Scarm, Malebranche of the Burning Abyss in my hand, and Special Summon it to a Zone that Topologic Trisbaena points to, how will the effect of Topologic Trisbaena be applied?
A: In this scenario, the effect of Scarm, Malebranche of the Burning Abyss that destroys it is applied immediately, and the effect of Topologic Trisbaena activates after Scarm, Malebranche of the Burning Abyss is sent to the Graveyard. Since Scarm, Malebranche of the Burning Abyss is not on the field, only Spell/Trap Cards on the field are banished and damage is inflicted accordingly.
