So I didn't do one of these for Stormwind because I wasn't really in the mood at the time, but apparently someone else picked up the slack on that so we're good. This miniset doesn't really seem to have any super complicated achievements because I've already completed them all with very little overall effort (although that might vary depending on your collection). Anyways, here goes as usual:
Even Playing Field
Tedious but manageable. JUst fill one half of your deck with card draw and the other with minions with 1-3 attack and upwards of 4 health (Silverback Patriarch meta pog). It'S gonna take a while and it is boring as fuck, but with only 20 hits total it's doable. Something tells me they used to have more and cut them down during playtesting after the Sigil fiasco.
?Por Que No Los Dos?
Same grind as the previous one, although you can speed it up with Moonlit Guidance to create extra copies. Bouncing the Jerrys also works.
Carrion My Wayward Son
Apparently bugged as of now, but should be easy to complete. Not sure how the game tracks triggering different Deathrattles over multiple games, but basically all you need to do is switch out your Deathrattle cards after each game. If you manage to build a deck without beasts you can easily tutor for the Parrot as well.
I Prefer Leftovers
Requires a bit of setup. You can use the Quest to get +3 spell damage and then fill the rest out with Talented Arcanist, Imprisoned Phoenix or Aegwynn. Alternatively, double Phoenix set up into a single spell damage minion also gets you there. Use Terrorguard Escapee to guarantee a 1/1 to shoot.
Robin Hood
Shield of Honor and Blessing of Might make it easy. Make sure you have your 1-damage ping of choice ready to activate Shield.
Should Have Seen This Coming
Possibly the most difficult one. The best way is to build a Shadow Priest deck with a lot of copy cards (such as Thoughtsteal and Mind Vision) and hope you find some burn or a sturdy minion. Everything else is just classic aggro gameplay. This is best to do in Wild because you get access to Mind Blast, which is cheap burst damage that allows you to get lethal out of nowhere and kill your opponent before they conced. Voidtouched Attendant also helps with damage breakpoints. Seance is very useful card for this one because you can actually choose a useful minion to copy.
Alternatively you can also try a more control based approach with a Mind Blast finish where you try to gaslight your opponent into thinking you don't have as much reach.
They're More Like Guidelines...
Very annoying if you don't own the two legendaries that allow you to cheese it: Lorewalker Cho and Valeera the Hollow.
First one means playing CHo, stealthing him with the stealth Gadget from Find the Imposter and possibly adding Divine Shield from Guardian Augmerchant and then hoping your opponent takes up the shenanigans.
The other is a bit more elaborate. You want to find both your Parrrley and transform into Valeera the Hollow. From there you play double Educated Elekk and play 3 Parrrleys, which then nets you a total of 6 shuffled into your deck once the Elekks die. From there you draw the remaining ones with Stowaway (or whatever else you want) and then hopefully survive long enought to play 5 more. Best done in Wild if you run into some sort of slow Priest deck. I was fortunate enough to meet a DMH Warrior who clearly didn't mind getting his entire deck swindled from him.
Thanks for the Loaner, Thrall
Best done in Wild. There are currently 4 6-mana weapons in the game. 2 of those are Epic, the other 2 are Legendary. This means that by equipping Doomhammer or Boggspine Knuckles and playing Suckerhook the next turn you have a 50% chance of instantly completing the achievement. Try until you succeed. It's easy.
Who Ordered Imps?
You need to trade 3 times, have an empty board and most importantly not run out of cards before you fully upgraded because you can't trade into an empty deck. Don't run more than 1 copy of Wicked Shipment, it'll only make it harder.
Hammer DOWN!
Trivial thanks to the multitude of weapon tutors in Warrior. The Quest is one, Corsair Cache is another two and if you really need it you can also get Forge of Souls.
Magician's Assistant
Best done with Rogue. You have access to Brain Freeze, Shadowstep, Potion of Illusion, and various poisons for 4 spell schools already. Wand Thief will likely get you a Fire spell (and an Arcane one too if you don't own Potion). Additionally you can use Shadowjeweler Hanar to get yourself a Holy Secret (or a Fire one too)
Sneed's New Shredder
(formerly Chuck's). JUst throw him into any of the other decks (except DH). It takes a while but it'S not so bad. If you want to target farm it, throw it in a Druid deck with Ramp and Moonlit Guidance for extra copies. Bouncing works too.
That's it, that'S all I got. See you next expansion.
