What abilities would be broken on a certain Pokemon?

I already know Pure Power would be broken on hard-hitting tanks such as Regigigas and Slaking, or even some fast sweepers such as Archeops and Pikachu holding a Light Ball, thus making their Attack as broken as possible. And we have Wonder Guard pure-electric types holding the air balloon. What other abilities could be broken on ceratin Pokemon or combined with certain items and moves?

Showdown! already has a format where Pokemon can have illegal abilities. Seeing how it’s so successful, I think all the broken abilities have already been banned. These are the banned abilities: moody, shadow tag, power construct, arena trap, comatose, contrary, fluffy, fur coat, huge power, illusion, impostor, innards out, parental bond, protean, pure power, simple, speed boost, stakeout, water bubble, wonder guardThe most broken ability/Pokemon combination that isn’t yet banned is regenerator on Pokemon that know u-turn or volt switch.http://www.smogon.com/dex/sm/formats/almost_any_ability/

Sturdy and Shedinja.

Shedinja has one hp. Sturdy lets you survive a OHKO from full health to 1 hp. Its basically immune to any attacks. Poison, burn, rocky helmet, iron barbs, sandstorm, recoil, hail, etc. are the only things that kill.
