interesting team tbh i was about to make 5 to 6 choice team before but im just too scared of it especially after seeing the might of stall. This team loses to well played stall team and if you lost rotom and sometime kingdra too Gyara can clean up the team.
I cant suggest what to use though(lol) and seeing how consistent gyara is as a top threats you cant just say its just gyara it sucks no problem.
I use Deoxys-D before it was cool
Yet i still use Torterra in OU
