Physical Latios is not a silly set. Dragon Dance//Outrage//Earthquake//Zen Headbutt/Draco Meteor/Thunderbolt/Recover is a viable set.http://replay.pokemonshowdown.com/ou-113417401
Where do I begin...
-Thunder Snorlax
-Protect+Toxic+Light Screen+Knock Off Azumarill
-Seismitoad without Swift Swim abuse
-Seismitoad having Drain Punch (against Azumarill) and Venoshock without a method to poison (unless it had Poison Touch, but it didn't activate)
-Special Metagross
-Camerupt in OU
-Dark Pulse Drapion
-Physical Latios
-Draco Meteor Haxorus
-Dewgongin OUever
And a note: even though Draco Meteor Haxorus is silly, other Draco Meteor Dragons aren't silly. Draco Meteor can be used by physiucally based Dragon-type pokemon to lure physical dragons. And Mixed Garchomp, Special Dragonoite, Special Salamence and Special MGarchomp are not silly.
