Lets review this card.
Getting a 1 Mana 1/3 weapon is great. It totally cost effective. Gives lot of value in early game. You can buff it with everything, 2x deadly poison+1 x leeching poison.
So it’s a 5/3 with lifesteal that is like the Paladin DK weapon.
Delays fatigue too every 4th turn.

Where do I see it’s token?

Shaku isn’t really important. You can add anything like second shadow caster maybe. I have seen other decks with Plague Doctor too so maybe that.

How important is Prince 2?

The Ultimate “5”
