I've never really thought of it as a good idea to "look" for KOs. I just take what my opponent gives me. I occasionally will encounter a fox player (any fox player) and when they get me to around 90ish, they start running up to me and Usmashing, since it's their most reliable kill move. But it's soooo easy to see coming, so I wait in my shield, then shield grab it.
Interestingly enough we play a character that relies on Usmashes for kills. Don't get me wrong, I go for purple Usmash kills all the time (and have been getting very good at landing it haha) but what if you play someone that likes to hide in their shield a lot? It'd be a good idea to continue camping them a lot, that way throws become another KO option. And the more KO options you have, the easier it is to get the KO. That's why I save my KO throws.
Totally unrelated: Dthrow-whitepikminlatch *****. There are a few variations of this. If you have a purple next you can sh white-purple toss and get another grab or whatever you can think of. You can standing white pikmin latch and then regrab too. You should only do this occasionally though, after you've conditioned your opponent to getting dthrown-usmashed/faired at 0%. I was getting people a lot with this, because I'd get that coveted 0% grab, but it'd be with a blue and a white next, so I said "eff it" and just threw the white, and it worked.
wow you guys all just mentioned like 4 major parts of my play style
uthrow with blue kills early, and yes it is EXTREMELY effective. no one expects it, and i even get some comments like "wow was that just a uthrow?" a lot of people except f/bthrow so they di up to stop their horizontal momentum, in which the uthrow kills earlier. It also kills at ~150% non-snake regardless, and is very effective. getting 150% on them is easy if you camp
dthrow white latch into a follow up is so good. A lot of people air dodge into the ground after you jump so you latch, they air dodge, you fast fall regrab WITH A WHITE PIKMIN ON THEM. I got a really good pit with that and in 4 seconds he was at 90% because of dthrow white latch. I also like the follow up mentioned here.
i never go for usmash kills unless i see the option or they are really high %. Most of my playstyle is grab combos, and grab ko's. I love to kill with uthrow because i never use it, so it allows me to combo with grabs, and stil have a decently reliable kill grab. Usmash kills are nice, but it's not bad waiting another 50% especially as olimar to go in and get it. My average kill on the enemy is ~170 or higher, unless i get a mind games kill
your lineup combo seems nice, i never through to go past and reverse pthrow into a grab...that sounds beast mode.
And yes, i lawl at the sight of me fairing into my yellows, yet i have a silent laugh so no one notices...it's too good, ****ing olimar is a sex machine
lastly, if we are mentioning small things....if you are edge guarding like a falco or fox or something, and you have a purple next and you grab the edge, jump off the edge, reverse purp throw their recovery. It also works if you drop below the stage, jump reverse purple and tether recovery, good mix up.
^^^^^^^^to go with this awesomeness, you can also do this with a white pikmin if you know you have to let them recover so you don't get yourself killed, get a bit of extra % in there, drop off ledge, reverse white, recover
