Woohoo I get a second turn! But on my second turn, can I play another Chance for glory to negate the effect of me losing? I mean technically I get another turn right? I mean if not that’s cool I just gotta know, ya know?
Even if you add another extra turn during the extra turn you take this way (e.g., because a Chance for Glory you control resolves during that extra turn), that doesn't change the fact that "[a]t the beginning of [the] end step [of the extra turn you take this way], you lose the game". "Tak[ing] an extra turn after this one" doesn't mean that the current turn immediately ends and a new one begins (review C.R. 500.7; compare Chance for Glory with Sundial of the Infinite; see also this thread).
