Yeah I have them, but I tend to save them for when my opponent is in a prime position. They usually rack up about 50% when I do them right.
And yeah, lucas has some amazing kills, I agree. I'm pretty sure it was scoot... I gave him a newfound fear of PK freeze *evil grin*
But yeah, i've also had times where the opponent has been offstage, i've PKT1 them into the bottom of the stage and they just hit it, fall down and lose a stock.
But some of the best kills i've had are with my brother. Last tournament, it stretched out so long that we had to make a train that we'd miss if we won the next match. We lost the first game, then won the second, and in the third, we both just went "Ahh, we can't afford to WIN THIS!" and just started running around and pretty much spamming up-smash. We lost, but we got some pretty hilarious kills in doing so. If we'd had more time I think we could have won it and secured second place in doubles last tournament hehe.
Ness also has some insane-crazy kills that no-one expects though. For instance, today when i was versing dre, he tends to use bowser's slam attack (I think it's down-special) to get to the edge when he's high up vertically. I was ness in one of our games, and used PK flash, put it under him, and just as he started going down, let go of B. I don't know how I managed to hit him, but the result of such luck was truly spectacular
. It's been recorded, so when it comes out i'll show that instance to you.
