I still hate how that's one of Lincoln's moves. Hell, I think a lot about his moveset needs a rework. You can tell they didn't put nearly as much love into Lincoln's moveset as they did into Lucy's. While some of his moves do reference things he does on the show (the squirt gun, the bike, Card Scatter, etc), most of it feels like "throw in a bunch of kid things and call it a day". He never uses spinning tops or plays baseball (granted, Lucy doesn't bite people and can't teleport or anything like that, but her moveset as a whole still feels much more inspired and cohesive). He uses a yoyo in one scene of one episode yet it is suddenly key to his entire kit here (was it just to be a Ness reference? The yoyo's fun to play with, but it doesn't feel very Lincoln). He now has his magic, David Steele gadgets, ARGGH ghost-hunting equipment, stuff from the movie, h*** you could throw in even more Ace Savvy moves! There's a lot of material in-show that they could use to craft a more inspired moveset.
Also, get rid of the gross diaper move. Lily doesn't wear them anymore.
