My only real question with this was the timing. Does Wildfire care to see the card in the yard at the time the trigger is on the stack or when it resolves?
To answer the timing question, yes, you can respond to the trigger and put a card into the correct zone (here, the hand), for example by cycling to draw a card. The newly drawn card will be in hand and a viable choice to cast (provided it's an instant or sorcery) for free when the trigger resolves.
If i end the turn with glorious end before blockers are declared after attacking would i still cast the spell from hand
Glorious End
No. "Attacks and isn't blocked" triggers specifically trigger during the Declare Blockers step if the creature in question is still an attacking creature at that point in time and nothing is declared as blocking it. If the Declare Blockers step doesn't happen at all, the ability won't trigger.
