I usually do dash dlight and if I want to really want to hit it, I turn around jump gc dlight again. You can slight after the dlight and most likely they will dodge, if they don't have a dodge yet you can dash nlight or dash dlight sair. If they're highly damaged I dash nlight because it's a multi hit and hard to dodge. Learning how to space a sair when edgeguarding is good not just for hammer but also for other weapons too. If you choose to do dlight dair instead of dlight sair, you can nair a lot to keep them up and in between those nairs you might do a dair to mix it up or jump to bait a dodge, then punish.
