Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This is a BUILD not a GUIDE. I'm merely showing how I build poppy. I play fairly consistently due to the 2 rushed blades of avarice. If you get a couple kills early game you could skip the second one and go for another zeal or something. Remember that items and skills are all situational so there isn't any particular order you should be adding/buying them. Late game you could turn one of your blades of avarice to a youmuus or sell one for a phantom dancer or something. its all up to you.
