My first guide, I'll probably end up revamping this at some point with more testing. Taka isn't my hardcore main, I thought I'd post a guide for one I use.

T^T My Paladin Taka would beat your juggernaut... Without any source of potential damage, or the ability to face off against another Enemy hero, wouldn't it be kind of useless? Also, this build would only theoretically work on squishy heros. Saw would have a higher potential threat value, because you have no way of harming him, Krul isn't that much of a threat, because all you have to do to defeat Krul is to Kaiten, XRetsu, then Kaku away. You just wouldn't want to get hit by his SwordUltimate.
Another thing, getting a crucible first would allow enemies to push harder, and thus game an early game advantage. And I don't use journey boots.
