If 2 monsters that have optional triggers are summoned at once will you only get to use one of them?
Example Dimension Fusion gets Stratos and DMOC. Can you use both monsters effects? I thought you could only use one of the 2, but in the SJC read it had this happen and both got their effects. Which is correct?

I am pretty sure that the SJC was correct, you can use both effects.

They're summond at the same time, it's an SEGOC situation. The last thing to occur was their simultanious summon, yes, they both (all) get their effects.

Man, I missed so many opportunities then. That sucks, but good to know. So basically it's just if summoned mid chain that it could miss the timing, like with Magical Dimension summoning DMOC. You can either use DMOC or Magical Dimension's monster destruction. Thanks.
