So I ended up catching an... interesting Zygarde. Brave with IVs of 31/31/31/21/31/1. I kept it in case Zygarde-Perfect ends up not gaining any speed, maybe I could use it under Trick Room lol... I also soft reseted a Brave Arceus with IVs of 31/31/31/0/31/0. Why am I getting all these Trick Room SRs while Cresselia continues to be a bastard about it ;_;
Anyways, because of that, I basically sucked Y dry of any legendaries, and have now erased the game so I can soft reset for a new Yveltal (probably either Adamant, or a better Hasty one than I have now).
To make things a bit less boring since I've gone through this game like 4 times now, this runthrough will only consist of perfect bred Pokemon I got in trades and never trained. This has made the team a bit... weird to say the least!
I currently have: Sheer Force Totodile / Braixen / Protean Shiny Frogaider / Shiny Seismic Toss Kangaskhan with its mega stone / Milotic / Roserade. So far, they're basically destroying the game, probably because of their perfect stats and the fact that I Super Trained them just so they could be EV trained without being high level lol.
Here's hoping I can blast through the game and not spend too much time soft reseting for Yveltal! Also, I nicknamed my character Softresetti with an angry face because I actually hate soft reseting...
