I know that Heal is a newbie Summoner Spell but it rly helps to trap greedy enemies under your turret and get an easy Kill or even a Double Kill,using Toss or Ultimate,and survive.This build is great for solo or duo lane and makes early Dives a lot easier when u're ganging and u are not willing to let your opponent survive with ****py HP.
Item Build depends a lot on your enemies and who's the biggest threat for you and your team...for example i may get a thornmail right after warmog's or i may get a Veil instead or rylai's...When all Items are set sell philosopher's Stone to get a free slot and build the final one before u start buying Elixirs.
Looking forward for your judges :D
