I wanted to write a guide for this deck on reddit for a long time now, but didnt have much time to do it, or motivation. Now i have both, and i will post it here. I think im more then qualified for writing this guide because i got to top 25 on EU server with it last month, and eazy legend this month with 43-19 score even tho i didnt have much time to play ladder.

Everyone probably already know that DR Hunter is midrange deck, which heavily relies on deathrattle sinergy with eggs and kathrena to get sticky minions on board and then cube + trigger it. 

I will talk about muligan in some match ups, and game plan. Pretty much you always want to keep eggs and keleseth so i wont mention it later.

vs Aggro(mid hunter/odd paladin/tempo rogue/zoolock)

Against aggro decks dr hunter is quite unfavourable, but this build with tar creepers and amani war bear instead of charged devilsaur is much more defensive then usual dr hunter. If you are facing aggro decks keep candleshot, flanking, tar, maybe grizzly if you are on coin. Fight for board and tempo, try to survive until you make it to kathrena.

vs Mage/Druid/Warrior

Great match ups. Doesnt matter what deck they are playing. Keep kathrena every time, eggs, cube, maybe flanking against mage just in case its aggro. Keep rexxar against warrior. Try to put as much pressure as possible.

vs Priest/Warlock

If you are facing bunch of priest change 1 tar for 1 nerubian and amani for charged devilsaur, play around scream and hysteria. Against warlock keep spider bomb for giants, and ooze for skull.
