This is a reasonably cheap, simple beast Hunter deck. Unless you are new to Hearthstone, I don't think a guide is necessary.

If you are new, then the aim of this deck to is keep summoning minion threats, whilst clearing the field ahead of you with removal.

There are a few spells (Master's Call and Hunter's Pack) that are for mid-late game card generation. You probably don't want to cast them before turn 6.

The only nuance is whether to keep the Kill Command in hand until you've cast Zul'jin to avoid hitting your own minions.
