Actually, it does.

Mega Mewtwo Y and the massive Speed buffs (Being at least able to reach escape velocity in its default form, and becomes even faster there to the point that time slows down around it as it moves.) that come with it (Not to mention not being limited by time like Super Shadow/Silver is), Protect/Barrier/Counter/Confusion to block, counter or reflect Super Shadow's attacks, Recover to heal any damage it takes on the fly, stat/ability-changing moves (Disable, Power Swap, Amnesia, Safeguard) to either buff its own abilities or limit Super Shadow's, and being able to utilise its telekinesis in conjunction with its more powerful attacks (Psystrike, Psychic, Psywave, Aura Sphere/Shadow Ball, Future Sight, Me First and Hyper Beam in particular would be useful.) would allow it to fight on more-or-less equal terms- or at least not to the extent of simply getting "obliterated", as you put it.

Still, regardless of who wins, it mostly likely will either last until Mega Mewtwo Y is fatally wounded, or Super Shadow runs out of Ring Juice and turns back to normal. Whichever comes first, I doubt it'd be an "obliteration"- since they're both very powerful and durable, it'll most likely be a drawn-out and bloody war of attrition.
