Battle Institute and online have been pretty beneficial for the growth of my trio...
Greninja has seriously cranked up my Battle Testing average with his sweeping, but ran into a bit of a wall once they started to roll out the Trick Room Pokemon. Will have to look out for that. I am thinking of changing up his moves a bit, so perhaps U-Turning out of scenarios like that would be best. I kind of want to raise a 2nd one as well...Just so I can play around with the rest of it's movepool. The sheer amount of trickery at it's disposal has always been very appealing to me, and I feel like I'd be missing out if I didn't try my hand with more than one.
My starter Delphox has just been a joy all around to battle with xD Wiped her junk EVs from the main playthrough to start all over again. And initially went with a sweeper moveset, but the Institute gave us a few lessons...She kept getting stopped by Pokemon that were either walls or had strong type advantage. So we went ahead and opted for something different that surprisingly worked wonders. Had this one Battle Spot match where she straight walls the offense of a Mega Kangaskhan and a Goodra back-to-back with a Reflect (from a teammate that fainted earlier) supported Will-O-Wisp, and a Mystical Fire/Light Screen combo...I couldn't even believe what I was playing for a minute, lol.
Part of it most certainly lies in how predictable that Kanga's Sucker Punch is. Let us set up the initial Will-O-Wisp, and the Light Screen for when Goodra was going to come out. At the same time, said Goodra's Special Defense kept it going by a sliver of health more than Delphox in the end. Which is why I then opted for Psyshock instead of Psychic...
(I KNEW I SHOULD NEVER HAVE REMOVED IT. It's been a pretty fun moveset, particularly with the right out-predictions. And very..Mage-like.
Lastly, Chesnaught's Spiky Shield and Leech Seeding...It's okay, but I have not really enjoyed my time battling with him as much as the other two. Especially when another Grass type rolls along...(Like at the Institute...Against another Chesnaught...). Thinking he'll find better times with a straight edge Physical setup. Takes greater advantage of his Adamant Nature and Attack training anyway. And his mass variety of offensive moves. Should be fun.
EDIT: Changed my mind. My Greninja's special sweeping is too fun to swap moves off of :3
And for Chesnaught...Keeping Spiky Shield, but no more Leech Seeding. We'll leave that kind of thing to a purely defensive Pokemon...Having 3 grass attacks on a hulk like that makes gameplay very dull.
