My new favorite "Fun" build

Hybrid Soraka Top.

Wait, hear me out.

Start Spellthief's. Level Q first. Use all 3 charges, then start CSing. Whenever there are no minions low, throw down an auto on the enemy laner. Get W second. Only use your Q for healing at this point. You should be able to safely sustain and poke until you can get some components of Frost Queen's and boots.

Once you finish Frost Queen's, poke like crazy. You should have your E and multiple levels in your Q, so use your E to redeem charges since it is instant.

Max Q, now you have a 250 dmg nuke with a slight delay on cast time. The thing with Q is that it's hard to land because it's so slow... right?

Get Swiftness boots and the Furor enchant. Afterwards, start building Frozen Mallet.

Technically, this is the only core you need. It's hilarious watching an enemy melee with no/few gapclosers trying to chase you or run away. Your damage is mediocre at this point, but you have all the time in the world to dish it out as they run away. To top it off, your Q is incredibly easy to land and you can full heal off of kiting one enemy.

The last items are situational. You can build Runaan's if you want to slow the entire enemy team in teamfights. Buy Nashor's for more ability damage and more onhit damage on your autos. Enemy team is Tanky? Get BotRK. You can already keep them at a distance with autos, why not shred them too? Iceborne Gauntlet + 3-4 second CD Q... lol. Infinity Edge, because muh damage. Merc Scim if they have a Malzahar. Rapid Firecannon to get that first slowing auto off. Rylai's because my parents hate me. Bloodthirster if you built mostly AD. WotA? Jesus this is stupid. Wit's End because free damage even if you built for utility. Zhonya's if you're a pussy.

Have fun (:

(Last game I played with this build, the enemy team joked about surrendering because I solo killed Gnar top 3 times)
