Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
It's funny how you were boosted to #1 while the server was down...
Anyways Lilligant wants the best coverage in Leaf Storm + move. That is why most run HP Rock, nice coverage. Specially defensive Heatran on a Sun team isn't appealing to me. Flame Charge would work so much better. Starmie doesn't really want Scald, I recommend Ice Beam.
Lilligant is my only hope at revenging Dragons and I have to use Sp def heatran to take hits from Latios. I'll test an attacking variant of heatran k :) seems to be the number 1 suggestion for this team
