Mercs are always your better option, since the only other ways to counter hard cc on Yi are Ancient Golem (which is debatable but I'd sooner take Lizard or Lantern on Yi) and Zephyr (which is also debatable but it doesn't give you Tenacity until you actually FINISH that 3k gold).

Bloodthirster is good but Infinity Edge is just better on Yi.

Hydra is pretty good for bursting and split pushing, if you're going to get Hydra then don't build Bloodthirster (or vice versa) unless you see more than one thornmail/sunfire on their team.

Black Cleaver is really weird on Yi since you'll rarely get all five procs on someone since they're probably dead unless they're a Taric or Rammus or something. That said, the armor pen it gives you can either get from Ghostblade (with even better side stats) or Last Whisper (which is just cheap). If you prefer Black Cleaver then by all means, do build it, but it is a weird path for Yi.

Frozen mallet is only good if you absolutely need the survivability, in which case buying Spirit Visage is better because of the magic resist that Yi needs to keep the AoE mages off him and to improve Meditate. The build path of FroMal isn't good and it's expensive as hell for what it does. At that, as Master Yi I doubt you really have to worry about sticking power as you're immune to slows and can move at like 500 units/second.

Last Whisper is good to rush after getting a good damage item or two. Infinity Edge is something you should probably be going for ASAP because of the immense damage it gives you.
