Normally I come in here and blast the absolutely bad cards, but let's play devil's advocate today...
First, ask yourselves a simple question: what makes Mewtwo Rumble better than Mewtwo MD?
Two little things:
#1) Stronger damage attack
#2) Higher HP
Now, what makes Mewtwo Rumble worse than Mewtwo MD?
#1) Lack of Energy Absorption
#2) Lack of Recover
Now, the final question: when would Mewtwo Rumble be a better play for its advantages over Mewtwo MD, despite its disadvantages?
I argue that with the rise of Garchomp C LV.X come DCE's release, this Mewtwo may actually have an edge over its MD counterpart ONLY because of the extra HP.
It's a given that if your SP opponent doesn't run a counter, then you auto-win the matchif Mewtwo LV.X gets out. Of course, the only way for a deck like this to avoid Mewtwo LV.X is by sniping its non-LV.X counterpart. If you do everything in your power to avoid that snipe, then your auto-win is that much more likely.
So if you value your auto-win that much, then this typically awful card may actually see play over MD.
Not to say that I WOULD play it over Mewtwo MD, but...It's a thought.
