Two words: Runic Bulwark.

Also, I main jungle rammus, and one game, my midlaner was getting bullied out of lane so hard by an AP yi. After finishing my tabi, spirit golem thingy, and bulwark, yi did absoultely nothing to me and I could 1v1 him (and did several times in the game.)  Taunt and Bulwark kept him in line, in teamfights, he'd alpha strike in for no damage and then I taunted him and well, that was the end of him. And btw, had he somehow gotten a reset, there's enough time when he leaves alpha strike to cc and kill him in under a second.
