So lemme yak about my Y team now that I have the game.
Delphox: I've been hearing a lot of mixed opinions of this thing. Bear in mind I have yet to complete the game (on my way to the seventh Gym), but except for its ability to take physical hits (his Rash nature doesn't help much), it's really come through for me when I need an ace in the hole.
Florges: Not gonna lie, this thing was a bit of a load. But now that it has Moonblast, its usefulness can only increase, especially since I'm giving it Calm Mind once I beat Olympia. Though once I realized Petal Blizzard was a physical move, I started to have doubts. May replace it in the postgame, though I don't know with what.
Blastoise/Mega Blastoise: A solid team member, but I kind of depend on that Blastoisinite for it to function, since it uses Water Pulse instead of the traditional Surf.
Heliolisk: Everything you need in an Electric-type. Fast, strong, moves that make it work.
Tyrantrum: It still has Rock Tomb and Bulldoze holding it back somewhat. But whatever, Strong Jaw turns Crunch into a third STAB. Still undecided on Rock Slide for safety or Stone Edge (or even Head Smash) for power.
Hawlucha: By far my favorite team member. I never got tired of Flying Press's animation, but there were times when the move's added Flying-type hindered Hawlucha's usefulness rather than helped it. It has High Jump Kick now, so barring the odd miss screwing me over, that should fail to be a problem.
