Forum:Cntinuous card effect queries

I want to know what would happen in these two cases of continuous card effects:

My first example is that I'm attacking with my Blue-Eyes White dragon to my opponent directly. Then my opponent activates Magic Cylinder which I chain to with Call Of The Haunted bringing back my Prime Material Dragon. In this case, would my life points increase by 3000 from Prime Material Dragons effect?

Next, my question goes to the field spell card XYZ Territory. So I activate XYZ Territory while I've got my Neo Galaxy-Eyes Photon Dragon already out on the field with three xyz materials. My opponent then chains with Solemn Judgement to my field spells activation. Can I activate my field spells effect to save itself from my opponents destruction trap by releasing an xyz material from Neo Galaxy-Eyes Photon Dragon? --68.80.142.179 (talk) 18:43, November 19, 2012 (UTC)
