The Biggest Hunter

These are the core cards you want in order to apply pressure early; due to a lack of removal tools, you can have some trouble removing big threats immediately, luckily, you have some pretty strong cards to fight on board; you want to be setting the pace, not responding to it.

Consider adding removal tools like Deadly Shot, or potentially even Vilebrood Skitterer to better remove threats in the mid-game.

Alternatively, a secret variant could work, due to strong early game delay tools, and lots of removal, as well as access to Zul'Jin.

I don't know why I'm adding this to the mulligan section.

The only real deviation against Aggro is that you want to see a taunt card as early as possible, Animal Companion and Witchwood Grizzly are great options, and Hunter's Hatchet is no slouch in the early game either.
