Mostly posted so I could show flippyflop but the deck is pretty good. I made and played it before the Crow buff so it's even better than that. Plunderer could be Unseen Commando and maybe one more Protect. If you do that it might also be worth swapping Kothon for Dusk Raider and Vanquisher's Blade for Vanquish.
But if you like Hooru Tempo decks you're in luck because that's been my favorite archetype since I started playing in set 1, and I just posted my best version of it yet with a detailed deck tech. It's pretty different than this one but the playstyle is the same and I think it's a lot better. Plus it's cheaper since it doesn't have Plunderer.
Oh man I totally forgot about Cleaver. Yeah Plunderer would be very good with that card indeed. And if you go Shadow there are some other good weapons like Hair-Trigger Pistol and Thief's Pick. Also Horrifying Helm is hilarious on Plunderer. You'd get a wombo curve of Plunderer -> Horrifying Helm + Thief's Pick to Pilfer and swing for 16 unblockable on turn 4. Plunderer would have one health but you can change the order of the weapons to get 2 health and 14 damage. I think that's the type of thing you want to be doing with her.
The problem is her body isn't something you ever want to play in constructed (it's basically an expensive Scaly Graun) so you need to get a lot of mileage out of the textbox. The best way to do this is to play weapons that have an expensive and/or powerful spellcraft effect, plus a lot of buffs for the berserk. I'm pretty sure you need both for it to be worth it and Hooru only really has buffs - the power from its spellcraft weapons mostly comes from how cheap the spellcraft is and the fact that the weapons are pretty good un-spellcrafted. Your best option is Bracers which is really good, but the second best option is Linebreaker's or Vanquisher's, and those are good sometimes but usually pretty mediocre.
So yeah I think you want her with either Cleaver or Sword of Unity because those give you really strong spellcrafts and good buffs. Also Time is the best faction to take advantage of a 1/4 - it usually wants blockers and you can buff it for free (kinda) with Stand Together and Xenan Obelisk.
more people to play Acquisitive Crow and Copperhall Bracers!
yea i think, i'm really not a huge fan of Dusk Raider outside of the feln berserk deck. the card just feels bad in general and i can see why people were cutting it from the skycrag aggro lists of late.
Kothon, the Far-Watcher is definitely a sweet one, it's just a shame that the endurance from Linebreaker's Shield is wasted on it but it's still a nice body for bracers.
i'm going to point to a conversation i had in another list in regards to Horde Plunderer but i see you've already accounted for it.
i think in the case of this current list i might just trim the maindeck to 1/2 and put them in the market or something and play the Unseen Commandos
You're probably right about Dusk Raider on average, but it does definitely win games sometimes. But without any nightfall synergy or guaranteed ways to draw units it's probably not good enough.
