Kyreth it would take an absurd amount of luck for Megasaur to beat Skarmory, it IS a hard counter. Skarmory, can brave bird and roost away the damage, freely set up spikes. If skarmory is free to do as it wishes and Saur cant respond, thats a counter. When Skarmory can not only do what it wants but also threaten to kill Msaur, thats a hard counter. Leech seed wont do crap he has roost.
crazy_man Grass/Poison take neutral damage to poison, Msaur is the strongest of all the grass/poison types, he will beat them all. Pure poison can be threatened if you pack EQ onto your set though. Your right about that.
New World Order Saur has 4mss but its not as bad as you make it out to be, he still has many opportunities to be played and hit stuff, hard. 100 atk 120 Spattk is nothing to scoff at, it may not be the 170 on charizard Y, but its still very potent.
Tested using a Bold Msaur with NO damage investment, running the 3 common attacks Giga drain, Sludge Bomb, and Earth Quake

Blaizken cannot set up on MegaSaur he WILL die.
AGAIN ALL with 0 investment on mega saur yet MAX investment by the others, only using a bold nature.
You severly underestimate him. He can get revenged, but plenty of his "counters" cant actually switch in on him.
Msaur does not have the typing to be a sweeper, play him to his strengths; he has 5 team mates:)
