I think his moveset is going to look something like this:
dsmash-shovel
dash attack-potted plant
up-b-balloons
down-b-pockets things
side-b-put up tree/chop down
neutral-b slingshot
ftilt-boxing glove
up smash?-fireworks?
bowling ball?
dsmash is the shovel move we I saw think, I don't think it's a tilt because it looks like he came out of a charging animation for the first one
dash attack is the potted plant, I think that might be safe to say
up-b I believe are the balloons, could be wrong though
the next things are kind of weird because I saw 5 things that look like special moves (bowling ball, slingshot, tree move, pocket, balloons), but we only have 4 special inputs (neutral, up, down, and side). It could be like a character specific thing where like one move does something different depending if the char is grounded or in the air.
I think ftilt is the boxing glove, but for all we know it could be his fsmash or jab or something
I think up-smash is a firework type move. There's a screenshot where there's something that hit the other characters with villager standing next to it, but it could be an item or a stage hazard. I'm not sure if the thing shooting is from AC or not, but I think it'd make sense that it could be fireworks
His net wasn't shown in game, but he caught mario with it so it could be a grab maybe
