Make sure ur tanking or be a carry cause if ur tanking dont get all the kills. I would rush the merc threads because of the magic resist and the speed depends on there team u might wanna change into a ninja tabi. Then get tanky with a ruby crystal into a heart of gold for the 5 gold bonus the get another ruby crystal. Rush into a phage to suport with the slow for ur carries to catch up and kill or finish them alone if ur the only one. then when u get a gaints belt you should be around lvl 10 or 11 cause u should have pretty good farm with ur Q I would max the w first for the stun so they wont escape and u can land some damage on them. After ur done with ur frozen mallet get ur randuins so u can slow them when u engage in fights so they get slowed for ur team to catch them. then depending on there team after randuins get a force of nature unless if they have a ad carry like tryndamere and xin zhao then get a thronmail. After that then u should get even more tankier with a warmogs for more durability in team fights and make sure u check dragon ofter and if ur plying tank go get some wards. Now the last item so u can finally get some good damage our on the enemy team is a infinity edge so u can do huge damage from ur crits and damage. Then when ur done with ur build make sure ur team should get the kills so they can get there items and finish there builds so they will carry ur team to victory.
