How do we win?
By spamming an enormous amount & getting some very fun combos
What do we watch out for?
Bowser's jump height is actually decent, and he will try to force us to the edge - it's the ony way he can catch us. That means watch out for full-hop approaches and clever stage control.
At some point bowser is going to get underneath you, and then he has the advantage. Try to avoid this.
Stages to BAN/CP?
No idea - CP FD if you can, it's horrible for bowser in this MU
Tips/Tricks when fighting this character?
Do not, under any circumstances, approach aerially in a way that puts him close enough to upB.
Our usmash actually works in this MU - if he ever approaches from above, usmash will hit him for a nice 28%.
Videos?
There is a good set between xyro and someone else (kinser?) on youtube. To me it shows the MU is close to even as the bowser dies to a lot of samus' gimmicks that are very avoidable with experience.
MU classification?
slight advantage for samus. Sure we can spam all day but bowser is simply so heavy that it makes the MU more even than you'd expect. And when he gets us in the air it gets difficult.
