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.
Ok, this is my idea of a team that should work well together in a variety of ways. First, all of them have runic xp buffs. So at start, all have 6% additional XP gain. That being said, they also have the 8% from Zilean's buff, and the 5% from masteries. So in total, they have almost 20% extra xp. That, in of itself, will give the team a jump. On top of that, it's designed with Vlad mid (tank build), and then the two dps units laning with a support champ. (I'm thinking Taric would go with Fortune while Zil goes with Yi.) That allows max performance from the nukers. The item builds aren't necessarily easy things to get, nor did I include step-by-step instructions. Basically, they are my idea of a recommended build... so more like guidelines. Basically, build the dps units for almost all dmg, little defense. Build the support units to compensate for that. Vlad can be built however. I'm not a Vlad expert, so I went with tank. That being said, Taric can tank, so whatever you want to do. Hope this helps people.
