I loved this :). Cherish, I'll repeat, cherish these moments for we may never see them again after chapter 300.
I loved how Mashima included everyone (almost) in this one and made it flow perfectly. There were many fun moments but the highlights for me were of course Jellal/Erza, Laxus/Makarov/Maevis and ELFMAN/Evergreen LoL. Flare's apology to Lucy was also heart-felt, I wonder what kind of role Raven Tail will play from here on out.
That last page after the explosion is like a fun mini game, every time you scan it over you find something new and hilarious. ^^
The last panel with Laxus punishing Natsu and Makarov/Maevis crying about the bills got a smile out of me. It looks more and more like Laxus becoming the next "permanent" master/leader will happen, if I'm interpreting things correct.
