Yubel - Terror Incarnate

Since the effect to summon Ultimate Nightmare is optional, I know you can miss timing with it. If I recall, you miss timing if you tribute summon a monster like Destiny Hero - Dasher by tributing Terror. How about if you tribute set? Do you still miss timing?

I know that with Geartown if you activate another, you miss the timing of the first one but not if you set it so...

you still miss the timing.

The reason why geartown does not miss the timing is, that it is destroyed by game mechanics at the same time the new spell is set.

Tribute Summon or Tribute Set: Here the tribute is a cost for the monster summoned/set, so it always occours bevore summoning/setting it.

Okay, figured. Thanks.
