For a combo turn he's an extra body played for free before the death rattle breaks. On a set up turn when you build some patron board he is a decent enough taunt that you can drop alongside them to protect your board. Extra three dmg from warsong, adds to frothing dmg buffs with whirlwind effects and the low to free cost cannot be understated in a combo deck. With that said though it's a one of imo.
As far as your sub goes idk maybe something like a taskmaster, inner rage, and anything you can include to get more draw would work too.
