So I attempted EoSD extra again, feeling like I can get a better clear. My clear had only 1 capture (lol safespotting Laevateinn), while I've captured much harder cards on failed runs (hello Starbow Break, Kagome Kagome, and Four of a Kind).
I stupidly bomb the death fairy, then I go, ah well, run failed, might as well bomb Silent Selene twice just so I won't be able to panicbomb Royal Flare and maybe I'll actually learn it. I proceed to freaking capture Royal Flare, and then to my stunned disbelief, capture Philosopher's Stone immediately afterward. I have never once caught either of those prior to this run. And then I proceed to dodge the books and Cranberry Trap in ways that just had to be seen to be believed.
Fell apart later on and didn't get the clear, but damn was that an epic two minutes or so.
