lol i havent played bww in months and yea i guess i have been getting a bit worst because im spending so much time on mk

and on bww's guide you should add some strats

short hop aerials
this is a fast approach where you take one short hop and then use aerial combos. so basically just dash to your oppenent and combo them from the air. my favorite would be dash>Fair>Dair>Dsmash. theres many others that work great.

Jolting
this is great to use on heavy characters. all it is, is 1 or 2 hops followed by a thunder jolt with some other combo. you can do it in place to see how they react, you can do it foward and then follow up with an aerial smash combo, you can do it backwards to keep distance, and you can use them at the same time as a way to play mind games with your opponent.

thunder guarding
use this as a way to prevent your opponent from returning to the stage. you can stand on the edge and thunder, you can jump off the stage and double or even tripple thunder (dont tripple unless youre very good with quick attack). they can air dodge a single thunder so a good strategy would be to jump off the stage thunder use your double jump and thunder while going towards the stage.

QAC
QAC = quick attack cancel. its a very complex strategy but is extremely effective once you master it. it can be used offensively defensively or just a way to play mind games. to QAC all you have to do is quick attack into the ground. this is very fast and the combos out of QAC are endless.
