I generated a lot of gold.
I played Maokai top and made the 2nd most gold because I realized there's a synergy with Zz'Rot and Banner with Ancient coin. If you let ZZ'Rot/Promoted minions kill things with an ancient coin, it gives you gold twice because it counts as an ally killing it AND you killing it. So if your Banner minion kills a siege minion, you pick up a coin and get ANOTHER 25g (40g with medallion+) on top of the siege minion's gold. I made more gold than the 7/2/10 Warwick by 200. I made over 2300g with my 3 gold generation items+Kleptomancy in a 25 minute game, killed 2 turrets and 3/4 of the inhib turret. https://i.gyazo.com/e06aef92ca662d0a8bac75afb13a1a48.png Also, you take item CDR+cosmic insight for obvious reasons.
Just a fun build that makes it really hard to lose. Doesn't have to be Maokai, you should probably do this as a support or any tank (because you'll have 200 armor and 150 mr total after 2 items). I'd also recommend Zilean because I used to do it on him all the time and just never die.
