>>40258327No its not conjecture its actually extrapolation based on the facts (ie lore) available to us and the logical conclusion time and time again based on the abilities and moves of each of these two pokemon and what they can do with them or in Mewtwo's case what we SEE hes able to with them tells us Mewtwo would be the victor easily as there are more ways to win then your brute force mentions and misconceptions about how energy works that doesn't fit the lore. Like giving Victini infinite strength and infinite Sp. Attack strength. We know that not to be the case.
