Forum:Dark Magical Circle vs Ultimate Conductor Tyranno

So the scenario is:

Opponent A has Ultimate Conductor Tyranno on their side of the field with at least one dinosaur monster either in their hand or field.

Opponent B has a Dark Magical Circle on their side of the field and a way to summon a dark magician on to the field.

It is Opponent B's turn: They (through whatever means it may be) summon Dark Magician (DM) on to the field. After Summoning DM, Opponent B chooses to activate Dark Magical Circle's effect of targeting and banishing Opponent A's Ultimate Conductor Tyranno.

Can Opponent A activate Ultimate Conductor Tyranno's effect to flip DM face down (assuming they fulfill the prerequisites stated on the card text) during the activation of Dark Magical Circle? Is it a matter of who declares their effect's first?

According to a ruling forum that I found online, the OCG ruling is that the 'flip face-down' effect of Ultimate Conductor Tyranno is a 'quick-effect', but it does not state so on the card text.
