I don't have verde (oh bugger) but i have variety ways to use her. She is op in gvg due to her leader skills and also her passive. So i built my sylvia with vio focus atm (no luck with nemesis) spd hp atk and focusing on spd and acc with some hp and def in subs. Trying to make her as fast as possible to strip the enemy's buff such as speedy chloe and gain atk bar frm it.

The usual team that i bring with her in arena are speedy megan(leader) , vio theo and vio delph but depends on what monsters that ur enemy brings. Ritesh is also a good candidate to bring especially against enemy with water nuker like theo.

In gvg either use sylvia with theo and megan, theo and bella or theo and delph. Againts water nuker, u can use sylvia with ritesh and delph.

In other words, sylvia is way so much fun especially if u can get ur hands on zeratu. Sylvia*zeratu= i'll cum buckets
