How to deal with Guest1337 in map with many high place like cake factory?

Like he just push me down the high place constantly and his block make him unable to take damage and the fact that when i face with him i was playing 1x whose i believe weakness being high place so i got hard counter by them just running in circle up and down the same place. Literally how to play against guest in general? I hate his block ability so much he would take a spot in my most hated video game characters list if it wasn't for the fact i think he's kinda hot.
