I was wondering if Master Oakheart has a place in Hunter. The key here is that Tundra Rhino is 2 attack. Question is, which 1 attack and 3 attack minions are good enough to justify this inclusion?
Infested Wolf, Timber Wolf, Tundra Rhino? That's quite a lot of chargers. Knuckles is another possibility. The issue i see with that is that those are all bad or so-so cards and then you're playing bad early cards to give a meaning to a 9 cost singleton in ur deck which is a no-no.
Compare to something like Lock:
1- power Voidwalker, malchezaar's imp,
2- power Imp Gang Boss, Dirty Rat/Deathlord (if control), vulgar homouncolous,
3- power Belcher, Voidcaller, Voidlord, Southsea capt (if zoo), jaraxxus
Those are all cards that you already want to play or are somewhat borderline. Voidlord or Jaraxxus are some ridicolous amount of stats. I think you almost always want the taunts so that the other deck can't simply ignore the stats. Belchers, humoncoli, voidlord, voidwalker, deathlord etc... then nzoth the turn after and laugh.
Other possibilities could be slow midrange shaman ( Trogg, totem golem, jinyu waterspeaker, thunderbluff valiant, al'akir, but you lack a 2 power drop) and taunt druid (hadronox, grizzled defenders, random taunts). Pally has decent assortment of 1-2-3 power minions but it has call to arms which is just broken and better as it get 3 minions by itself already for only 4 mana.
I doubt the card will see play outisde of lock though. It seems such a good fit in there.
