Forum:Various questions about priority and summons

I checked the Priority page and several of the related pages but still cannot find the answer to my questions. I'm confused about how "priority" works mostly about summons. 1) If I summon a monster who has an effect on summon (Caius,Gyzarus,etc.) and my opponent chains Solemn Warning, would calling priority still allow you to use the effects (remove a card, destroy 2 cards, etc.)? I think it would be no since the summon was negated. 2) If I negate the summon of cards such as E-hero Absolute Zero/Yubel - Terror Incarnate with Solemn Warning, would the effects of them still work? I also think no to this since the summon was negated it probably shouldn't have touched the field at all. 3) If a card who's effect activates when a certain monster is summon (Harpies' Hunting Ground,Gateway of the Six) and I summon one of those monsters who's summon is negated by Solemn Warning, would the effects of them still work?

Extra (Involves OCG so just ignore this if you don't know the answer): Would you be able to chain Aggressive Move to Bottomless Trap Hole which was chained to a summon of an Inverz monster in order to save it? If so, would you still be able to activate and resolve the effect of Inverz Morth/Inverz Gilafer or would they miss the timing?
