Jeez... I should *not* be having this much trouble with a non-heroic boss. WTF Grobbulus?
The non-heroic bosses this week are significantly harder - normally I pick a random deck to beat them with (which in practice is either my common-only druid or a herp derp aggro warrior), but this week I actually had to think about what deck to use. It doesn't help that Grobbulus has > 2 copies of his special card Mutating Injection.
Edit: I've been meaning to try out Weblord, but I haven't found a good reason to pick it arena. By the time I see it, I usually have some battlecry minions already, and I can't justify a 1/4 that hurts both of us equally. Seems useful in Druid decks though - it disrupts your own taunt givers if you're playing Watcher Druid, but your Ancients are fine, Keeper is fine, Druid of the Claw is fine, and it doesn't hit minions with Deathrattles.
Yeah the bosses were definitely harder this time around. I had to build a special deck for Patchwerk and Grobbulus.
But man, the Heroic bosses are a nightmare. I managed to beat all 4 of them (super yay!), but it took a few hours. They were ridiculous, at least given my limited card collection! I don't know where to begin describing the decks I used to beat the last 3 bosses without showing a full decklist.
Okay, Heroic Patchwerk is actually pretty simple:
Try a twist of Freeze Mage. You now have new tools in the form of Mad Scientist, so take all the Ice Barriers/Blocks you can find, and maybe Duplicate for good measure. Also ready your Frostbolts, Ice Lances, and Mirror Images. The goal is to stall as much as possible while dropping lots of cheap minions that overall aren't too devastated by the insta-kill hero ability. The boss likes going for the face, so take advantage of the minions you can keep on the board to slowly whittle down the boss's HP. From here on, it was all riding on luck
Grobbulus:
Yeah I don't know. It started with a Lightwell that I managed to buff with PW:Shield and later taunted with Sunfury. It ended with me summoning Thaddius (yeah... and I superfluously buffed it with Divine Spirit too). Try sticking with 3 health minions to avoid slime death and heal them up when possible. Egg is still good here though. In addition to that, I used Mass Dispel at a good moment and even Velen to strenghten my position (use what you got, I guess). Holy Nova is quite good here. Gluth: Probably the hardest of the lot. The worst part is that the weapon he uses buffs on the death of your own deathrattle minions too. That's absolutely cruel and just further limits your options.
I used a variation of a Hunter UtH deck that included 2 Oozes, 2 Multishots, 2 Deadly Shots, and 2 Kill Commands (and a Hunter's Mark helped too). All of those will find use here. I think you just have to survive off the Zombie Chow until you get lucky and flip the board with an opposing Abomination at a point where Gluth doesn't have the weapon (almost surely because you destoryed it somehow). I ended up with board control by the end, with Highmane as my biggest minion. Not even sure UtH is helpful, as Unstable Ghoul (mini-abomination) makes short work of the lot.Thaddius:
Would you believe I won this on the first try, with the exact same deck I ended up using to beat Gluth? All around, this has got to be the easiest fight around just due to how badly Thaddius can screw himself over with his hero ability. The only extra challenge in Heroic is that he starts with Stalagg and Feugen. I guess I won because Hunter has good removal at fairly low mana (Deadly Shot, Kill Command, Hunter's Mark).As an aside, I was wondering if it's worth including just Feugen (the 4/7) in a deck. The 4/7 stat balancing is fairly decent for a 5 mana minion. The opportunity cost brings it down, but the deception of making your opponent think Stalagg will follow can have subtle positive effects overall. They may save silence minions and hexes for a minion that will never come, and you don't have to worry about that lame 7/4 remaining dead in your hand.
Edit: looking online for guides, it seems
Alexstraza isn't auto-nullified in this quarter, so yeah I guess Freeze Mage beats them all.
