Brief guide of how the combo works:
1.1. Complete the quest while setting your opponent to the lowest possible health.
1.2. I'm still not sure if fire fly is a must for completing the quest, testing is required. Other cards being considered:
Glacial Shard-> Pretty powerful aggro card IMO.
Worgen Infiltrator-> Same as glacial shard.
Leper Gnome->secured 2 damage.
Raptor Hatchling -> I have a dilema with this card. I like the stats and the beast synergy but dislike the fact that the deathrattle means less odds of drawing hemet.
2. Play Hemet. ONLY PLAY IT ONCE THE QUEST IS COMPLETED and you have Queen Carnassa in hand!!!!!!!
3. Since you can't play hemet + carnassa on the same turn you will pass and 100% draw rhino. Play the hunters quest reward card.
4. Damage output from clear board:
10 mana= 2(Rhino)+3x5(raptors)= 17 damage
If you have saved timber wolfs you can end up dealing more damage.
10 mana & 1 wolf= 3(Rhino)+4x4(raptors)+1(wolf)= 20 damage
10 mana & 2 wolfs= 4(Rhino)+5x3(raptors)+4(wolfs)= 23 damage
5. Have Fun!
*Disclaimer. The amount of taunts and the unknown meta that is yet to come probably will make this list not being good. Still the list shows this combo which imo is reeaaaally powerful. Obviously with this list if you Hemet is at the bottom of the deck... well you most likely will lose.
Since this deck is increasing in popularity something which I didn't expected, before commenting what other people already said please read this:
Most of the cards (that are no hemet, rhinos or 1-drops) can be changed and build a more aggro or control oriented deck.
As it is right now the deck is designed thinking about the combo aspect (for fun), card cycle to look for hemet. But sincerily I don't think this exact list will work. IMO a more aggro deck which pics it's curve at 3, with the exception of Rhino and Hemet, should be the way to go. This can result in not needing hemet to win by playing Carnassa on turn 5 for a huge! tempo gain (5 mana 8/8 guys), and actually with all the fuel that the raptors give, (in case you draw hemet later) having a dead card in hand should't be a big deal. But trust me if you happen to have hemet on 6 and your quest completed or nearly completed (with 2 1-drops in hand) play it. Tinkering the deck like that will give you so much burst and instant board control, go for the combo if you can!!!. Think of the combo as it was Finja, If you have a decent deck maybe you win with out it, but if you get it and play it on turn 5 you know you will probably win that game because you snowball from there.
On the other hand, if the meta ends up being taunt heavy you can actually play a more control oriented build with 1-drops obviously but with removal such as Hunter's Mark, Kill Command or the new spell which all happen to cost 3 or less, perfect!
Once you have played Hemet you don't have to kill the opponent in 1 turn, remember that you get 15 raptors and the opponent will have to clear them turn after turn, maybe you draw both Rhinos and you can do 1 turn of clearing your enemy taunts and in the next turn put or your burst, it's up to the player.
I'm not playing hunter at the moment I'm missing marsh of queen so feedback should be appreciated. Just comment what card/s you substituted and why.
