So this team takes advantage of the fact that OTR Magearna is an absolute savage, and that smack down lando takes care of everything that OTR Mage cannot (celesteela, toxapex, heatran, etc.). Tang takes care of koko, ash gren, and keldeo. Protean Gren is here to click spikes and do some damage. Esens takes care of pex. Hydro hits heatran hard and is also there to kill medicham after 1 spike and rocks. Mega mawile can take advantage of magearnas TR, and it forms a nice fairy spam core with it. Scarfchomp makes sure i dont lose to volc or zard y. I have dual chop over dragon claw to have a chance to kill smeargle leads through sash (its about a 56% chance in your favor). Its weak to mega medi and a bit weak to mmeta, but they can be played around. Still, its a fun team and i hope you try it out! (Btw, make any changes you feel are necessary). Thanks!
