Hey, yall know about this? When edgeguarding as Villager, bowling balls and turnips spikes or nair/slingshot gimping (we have a lot of options) are the way to go, but we have another super awesome option.
Ya all know you can slow gyroid down when riding him by holding back, right? Good.
Well when you get most characters off-stage, use that and aim for the ledge. Now your just covering the ledge with a super strong hitbox. All they can really do now is...go around you? Only a few can do that! Lucario, ROB, another Villager. Lots and lots of characters have to go for the ledge, so...this is a super strong option, try it sometime!
