How to play as Gwen
Save Gwen E to dodge Yorick E or his cage instead of using it for routine poke; if his E misses, the ghouls do not jump onto you and you can trade or all-in.
Clear ghouls with attacks rather than spending a stacked Q on them, and look to pressure Yorick when his E misses or his Maiden is exposed.
Yorick E marks its target so his ghouls can leap onto them; Gwen Q's cone can hit Yorick and nearby ghouls, while a basic attack removes a ghoul in one hit.
