Tavern Brawl - Return of Mechazod!
It looks like you have to win to receive a pack. I apologize for the misinformation.
Update: Neviilz's Anyfin Can Happen OTK Paladin
Annoy-o-tron isn’t a bad idea. I believe Doomsayer is here just to absorb damage, or clear the board. It’s basically a stall tactic to get you further into the game, so you can unleash the Anyfin Can Happen combo.
Brian Kibler's Season 22 Mech (Tyson) Priest
Shadow Word: Death or BGH for Vol’jin. Ragnaros or you could go second Gorilla Bot for Dr. Boom.
Forsen's Season 21 Gorillabot A-3 Mech Mage
Second Tinkertown Technician and Loatheb. Or you could just do two Mechanical Yeti.
Thijs' Season 22 Freeze Mage
Kobold Geomancer is the most direct replacement, but some people believe it doesn’t work. You could try a second Blizzard or an Explosive Sheep.
Control Warrior Deck List Guide - April 2016 (Season 25, Wild)
That might work, it removes the Death’s Bite, Alexstrasza, into Grommash combo though.
Midrange Paladin Deck List Guide - April 2016 (Season 25, Wild)
This is almost a control deck, I wouldn’t be looking to put burst combos in it.
Surrender's #1 Legend Reno Jackson Warlock
Ragnaros would probably be fine. You could cut a Molten Giant and run the Feugen and Stalagg combo like this deck does: http://www.hearthstonetopdecks.com/decks/reno-jackson-warlock-deck-list/
Midrange Fast Druid Deck List Guide - April 2016 (Season 25, Wild)
Harvest Golem for a cheap replacement, or Mounted Raptor.
Forsen's Season 21 Gorillabot A-3 Mech Mage
Second Tinkertown Technician or you could try Loatheb.
Update: SuperJJ's Season 22 Malygos Rogue
The update just reflects what was changed from the last version of the deck. You should just use what’s shown, which would be one of each.
Update: Neviilz's Anyfin Can Happen OTK Paladin
Murloc Knight is pretty rare, I wouldn’t worry about it.
Secrets Paladin Deck List Guide - April 2016 (Season 25, Wild)
I haven’t seen much Equality in Secret Paladin, I have seen Repentance though.
Nope.
