I haven't used him much myself, but isn't Juggernaut solid now?
Luke Cage also has his occasional uses - this might be one of them.
He is but this fight can place petrify and it can be tricky
I'm going to have a go with him. Mines r5 and high Sig.
There are very few champions who can handle Languor fairly easily, and Luke Cage is one of them: you take a hit to trigger his Invulnerability, then throw SP3. (You can do the same with the other burst damage node, too). Luke is properly indestructible: you take no Languor damage.
Luke Cage is pretty good for this if duped. Just parry and get to an sp3, don't use it of course, when you're about to take damage from not using it get hit and you'll become indestructible and take no detonation damage. Then it's just a slow careful fight.

But usually the Parangon objective always leave you with 3-4 choices. Here it's really (too much?) limited.

Rinse and repeat...
