And what are they? Obviously Tankplank is a tanky build, but I know there's a lot more, like Bankplank and I don't what it is.
Bankplank is when you have avarice blade when there is a twisted fate in your team. With 4 gold extra per kill and your parrley, you can score some serious early game money . ( you can also include a philos or something)
There is Jayceplank, a Jayce build using IE, Warmogs and Atma's for damage of AD carry and tankiness of a bruiser. This is build, that works mostly only on GP and Jayce, because they are only bruisers with ranged attack that doesnt need to mix AD with AS (GP is limited only by CDR on Q and Jayce has Hypercharge for AS)
