Match-ups

Priest: Never a problem since a full 3rd of your minions are 4 attack and quite strong on their own. They can't handle total board clears very well either

Warlock: As long as it's a zooish variant then all you need to do is keep clearing and healing, making sure to use your aoe to full effect. It's ok to take quite a bit of face damage  as warlock just doesn't have the burst they used to and you can heal way out of their reach. If they are plating the quest then absolutely save geddon until after they play the portal and it's pretty much insta-concede

Hunter: Play for the board but do not over commit at any point, you want to always have more cards in hand. Pyro's are incredibly important here to take care of all the hunters tokens. In the end a favoured matchup as they don't usually have enough card draw to recover from 2 or 3 clears

Warrior: Pirate you crush, quest you get crushed

Shaman: Again, they can't handle this many board clears and usually draw too many cards if you can safely keep a mana tide alive.

Mage: Elemental is easy enough to beat just like any other board-centric deck, healing is quite important here. As far as the quest goes, if the mage is drawing like crazy it'll be giants combo, in which case spikeridge is your best bet to survive. If he's drawing like crazy, it's exodia, so you better board up as much as possible and pray you kill him quick.

Paladin: Can't think of a pally that wouldn't be board focused, so usual tactic of bleeding them dry applies. If it's a mirror against this deck (as if lol), I dunno, I guess don't play curator and maximse heals

Rogue: Tough one against quest here too, just make sure you get at least 1 equality combo, apply doomsayers liberally. You will have to rush face so try to combo a cheap clear with a beefy minion, steed helps a lot here as well

Druid: Might be hard to beat quest but I dunno who's playing druid anyway?

Combos are as follows 

Board Clears

Equality + Wild Pyromancer/ Consecration/ Corrupted Seer/ Primordial Drake/ Baron Geddon

Doomsayer + Aldor Peacekeeper/ Spikeridged Steed

Removal

Aldor Peacekeeper + Stampeding Kodo

Will add more stuff if there's interest
