Amaz's Viagame House Cup 3 Control Priest
I would only change the deck if I was missing other cards. If you really wanted to add them you could probably take out 1 Shadow Word: Pain and 1 Light of the Naaru.
Vorpal's Season 16 Face Hunter
Control Warrior, Patron Warrior, Midrange Paladin, and Tempo Mage have pretty good matchups. Midrange Druid and Freeze Mage are a coin flip I believe.
Amaz's Viagame House Cup 3 Control Priest
If you have Ysera I think that’s the best replacement, but if you’re going to put Dr. Boom in anyway than Ragnaros would probably be fine.
Forsen's Archon League W.1 Midrange Demon Zoo
Check out this Deck vs. Deck match: http://www.hearthstonetopdecks.com/versus/firebats-midrange-demon-zoo-vs-hypeds-oil-rogue/
You’ll find Mulligan percentages under the Demon Zoo side.
Silentstorm's Archon League W.2 Midrange Paladin
Here’s the VOD during the tournament, but I don’t think he gets a chance to play it: http://www.hearthstonetopdecks.com/versus/thijs-oil-rogue-vs-silentstorms-midrange-paladin/
Jab's #1 NA Midrange Hunter
It would be very tough to replace those. I’d probably go with a second Ironbeak Owl, and a second Piloted Shredder. Not having Mad Scientist is a pretty big weakness though.
Dog's Archon League W.2 Lightbomb Priest
You could put in a second Dark Cultist, or try Acidic Swamp Ooze if you face a lot of Patron Warrior.
Zetalot's Season 16 Shadow Priest
Acidic Swamp Ooze for direct replacement, or Loatheb to fill the mana slot.
SilentStorm's Archon League W.1 Midrange Shaman
You can’t replace him directly, but you should probably add a finisher. I’d probably try Ragnaros and see if that works for you. Sylvanas Windrunner or a second Harvest Golem could just fill the spot.
Firebat's Season 16 Freeze Priest
Acidic Slime Ooze for a direct replacement, or Loatheb to fill the mana spot. Second Azure Drake would also work.
Trump's Handlock Warlock vs. Orange's Face Hunter
The mulligan list is from all different Face Hunter decks and matches, so after a while you tend to see a lot of minor differences in each player’s deck.
Sjow's Season 15 Feign Death Hunter
Yep, this deck is very similar to Midrange Hunter it just focuses more heavily on Deathrattle.
Savjz's Season 14 Mech Shaman
You could take out Enhance-o Mechano for it maybe. Mimiron’s Head isn’t that great of a card.
Chakki's Season 13 Mech Mage
I wouldn’t make any changes, but Mech Mage is considered a weaker deck right now. It is, however, perfectly capable of reaching legend.
StrifeCro's Season 15 Dragon Warlock
You could do that, but the point of Imp Gang Boss is that it sticks something to the board.
Fixed, thanks!
