Forum:U.A. Ruling vs Breakthough Skill/Shikinaga

Hi, today i got a match vs Shadoll, and during the duel this things happens and i really dont know the ruling of these chains, can someone explain what would happen?

1. If opponent special summon Shadoll Shekhinaga, I chain U.A. Blockbacker, he chains Shekinaga, I could chain U.A. midfilder, what happens? Shekinagas loses his effects? Is U.A. Blockbacker destroyed?

2. On the other side, opponent activates El Shadoll Fusion, i chain U.A. Perfect Ace, he chains Breakthrough Skill, I chain midfilder, Is El Shadoll Fusion negated?
