Forum:Rai-oh vs. 2 Fusion Cards

I've seen Rai-oh's ruling it CANNOT stop Polymerization. Q1) So in a similar manner it cannot stop inherit Special Summons like Miracle Fusion/ Parallel World Fusion?

Q2) Can Rai-oh stop Fusion Gate? For Example: 10.7.11.54 (talk) 16:37, May 4, 2011 (UTC)DJVOLTIC
 * Let's say I have E-Hero Avian and E-Hero Burstinatrix in my hand.
 * Fusion gate is already up BEFORE Rai-oh hitting the field.
 * I attempt to Fusion Summon via Gate, can I do it?
