Rhino OTK Hunter

The combo requires a Thaurissan discount to deal more than 26 damage, but is extremely flexible. Sometimes you’ll find yourself charging in some wolf-buffed dragonhawks, other times you’ll go for unleash + alleycat + hyena to smash your opponent in the face, and sometimes just rhino + spellstone is enough.  You can get some crazy lethals with the combo, even through taunts: unleash and alleycats with a timber wolf buff can clear a voidlord easily and allow a hyena to go for the face. You really need to constantly be monitoring how much damage you can do.

Feel free to drop some combo pieces outside of the combo against midrange/aggro. Particularly against odd paladin, you often aim to win with a hyena + unleash board swing rather than waiting until you can assemble the full combo. Against such decks being able to play an upgraded spellstone on 5 is also really important, more so than the combo: discarding Thaurissan or rhinos in a tracking for a spellstone is perfectly OK. Doomsayer on 4 into spellstone on 5 is a really strong play that generally lets your 12/12 worth of stats come down uncontested. Against even shaman and burn mage in particular, spellstone is your main win condition, rather than the combo. 

Deathstalker can also be used to create new pieces for the combo: zombeasts with windfury or tundra rhino zombeasts can add additional damage.
