Yipes...I read the test results for this combo and was rather surprised to be honest; so much so that I figured I would do some tests of my own. Here they are:
**Standard testing procedures are used when applicable (i.e. use of TT attack stadium, alternating launches etc.)
Storm Cancer 100WB vs Flame Bull 145WD
8/10 in favor of Flame Bull 145WD
* I am aware that this combo is no longer top-tier, but my Burn is out on a loan and this will have to suffice.
Storm Cancer 100WB vs Earth Bull 90WD
8/10 in favor of Earth Bull 90WD
Storm Cancer 100WB vs MF Earth Bull C145WB
6/10 in favor of Storm Cancer 100WB
This combo peaked my interest mainly as I've tried using something like this before, and in fact I was beaten in a tournament with a similar combination. Against the Flame-based stamina combo above, it managed to achieve a couple of KO's, but nothing as spectacular and common as what is mentioned in the OP. The results against a defense combo do not surprise me in the slightest. It should also be noted that the combo did not destabilize the defense combo so much as it did merely out-spin it(not surprising considering the the weight and additional frictional force acting upon the defense combo). I really hate to sound like a downer, but it does not seem that this combo is quite as versatile as it is made out to be.
World's No. 1... or at least I was...
Ah well, cool while it lasted I suppose =P
