Tankplank should only be played by Good players! its hard to play him because he can suck terrible in the beginning!!
Dont think you can´t die only because it´s called "Tank"plank". Tankplank is an easy target in the beginning and even in late game he shouldn´t be the maintank because he don´t get high resistance.
as a lanepartner i prefer a tank with stun (like leona, amumu, rammus)

hint: dont use "Remove Scurvy" to heal yourself. Use it to remove stuns and slows ;)

Pros:
- high dmg and good crit chance in the beginning
- Easily farming
- high movementspeed
- much life in lategame (hard to kill)
- much dmg against lowlife champs in late game
Cons:
- high costs
- Not that much dmg against Tanks or semitanks

I choose Ghost and Exhaust
- its good to chase enemy champions or runaway from them

- you should farm with Parrrley to get enought money in the beginning
- in late game you dont need to farm that much
- you can do red and blue buff if there isn´t a jungler (its always good because the high manacosts)
