Well... my deck without PA would lose against any FG with permanent cotrol, because eternity is the most important card... my victory against octane when I was bumping a pharaoh proves that even pharaoh is not needed to win
(I could have bumped any creature), but eternity needs to survive...
But more PA really help against Divine Glory, Rainbow, Hermes, sometimes Octane, and probably could help against Obliterator if he plays a protected pulvy late enough... while I don't feel harmed much by PA when fighting against FG without permanent control, because I can discard it or play it on anything, and draw more cards...
I have 6 hourglasses for a reason - I use them to protect SoGs, shields and bonds from destruction, and I use them to draw cards as fast as possible (even if I have 7 cards in my hand I usually draw and eventually discard something less useful, if what I draw is not a pillar or something I can play - I only stop drawing cards when I either want to wait a while to gather quanta, or when I want to be able to use eternity a few times on my opponent before I have to start bumping).
I even sometimes play an eternity over an eternity, or a fog shield over a fog shield, or play a few sundials at once, just so that I can draw more cards before my hand is full
