By replacing your primary with spellthief's edge this requires you to max out your first ability and go straight for the third silence aoe as this does damage as well. all of the gear does well to reduce cd and give you more health which will better allow you to actually participate in team fights. But you need to land at least 80-90% of all your hits to see good gold outcome.

In lane do not die and if you play well the fairy charm should give you an edge on mana. you should be able to keep opposing adc bot lane from farming. ward as jungle will try and come. ward more. do not return to base until you have at least 1k or 1050 to get boots fairy charm frostfang and healthpot. port back keep up aggression so your adc can farm.

If all works well you cd reduction plus tank abilities make you a serious contender when enemies initiate anyone can be destroyed with a well placed silence and minimal team work. use you 1 to farm creeps when adc is not in lane. try not to ks.
