Role:Special Sweeper(Meaning , try and EV train it in Spc.Attack.You could Defeat a bunch of gengars)
-Blue Flare(His Second SIgnature move,Better then fusion flare since you dont have zekrom)
-Solar Beam(Coverage,With power herb works wonders on most Metagame teams)
-Extrasensory(Just for a little more coverage)
This is the moveset you should have at level 100.
You already have Reshiram as your fire type.
Switch with Galvantula.You have a small,but still there, Weakness to flying.
-Thunder(Compound eyes compound eyes )
Haxorus Is fine just switch out Dragon Pulse with Brick break and SLash with earthquake.
Krookidile.....Not so good.
Switch Foul PLay with crunch,Dig with Earthquake,
SAnd tomb with Stone Edge, and Sandstorm with outrage.
Unfezants fine although you could do with a water type, unless you find you really need one,
DOnt worry about it.
