Of course I am big mega sceptile lover and wanted to try him on a different team so I used it on this. Garchomp is standard and rocks. Mega Sceptile standard 4 attacks with Giga Drain over hidden power fire to keep healthy. Alolan Muk pursuits Lele and other stuff and my Rotom was initially max speed and max HP (248) but i felt we needed more phys def while outspeeding Heatran so i went with this spread. Latios is scarfed with speed control and trick for crippling fat. I played 4 games vs this and won for out of 5. Rotom Wash and Latios are the ground immunities. Iron Treads is 4 attacks with spin and Supercell slam for Zard Y and doing big damage to Corvknight. Rotom wash is foul play to punish physical set up but i am thinking of other options or twave.
