CaptainKaulu's Card Ratings

Meta-Defining

• Battlefiend
• Umberwing
• Eye Beam
• Kayn Sunfury
• Hand of A'dal
• Greyheart Sage
• Blackjack Stunner

Great

• Chaos Strike - best comparison is an improved Shiv
• Sightless Watcher
• Glaivebound Adept
• Twin Slice
• Blade Dance
• Priestess of Fury
• Skull of Gul'dan
• Furious Felfin
• Crimson Sigil Runner
• Fungal Fortunes - if Book of Specters could find a deck, this can too
• Zixor, Apex Predator - only in a deck dedicated to buffing him, naturally, but I think that could become meta
• Mok'Nathal Lion
• Pack Tactics
• Scavenger's Ingenuity
• Astromancer Solarian 
• Evocation
• Incanter's Flow
• Murgur Murgurgle
• Kul Tiran Chaplain - remember Kabal Talonpriest?
• Soul Mirror - it's like Lightbomb that doesn't hurt your own board and leaves behind compensation minions for every enemy minion that doesn't die, for just 1 more mana
• Shadowjeweler Hanar
• Serpentshrine Portal
• Kanrethad Ebonlocke - solid addition to solid Zoo builds
• Darkglare - will be the key combo piece of some meme deck, but will also just be in other decks
• Kargath Bladefist
• Bladestorm
• Imprisoned Gan'arg
• Maiev Shadowsong - overrated, not going to be as ubiquitous as Zilliax
• Burrowing Scorpid
• Guardian Augmerchant - will be at least as ubiquitous as Fire Fly

Good

• Shadowhoof Slayer
• Aldrachi Warblades
• Satyr Overseer
• Chaos Nova - very strong card, but for now I think the control DH deck's weakness will pull it down
• Consume Magic
• Ur'zul Horror - may not have room to be played because of an abundance of strong 1-drops in the competition
• Feast of Souls
• Altruis the Outcast
• Illidari Felblade
• Raging Felscreamer
• Command the Illidari
• Metamorphosis - overrated
• Warglaives of Azzinoth - overrated
• Imprisoned Antaen
• Fel Summoner
• Immolation Aura - not sure about the deck it goes in, though
• Spectral Sight
• Glowfly Swarm
• Augmented Porcupine - a personal favorite of mine, so I may be overrating it, but I don't think so
• Deep Freeze
• Libram of Hope
• Underlight Angling Rod
• Aldor Truthseeker
• Libram of Wisdom
• Imprisoned Sungill
• Libram of Justice
• Aldor Attendant
• Scarlet Subjugator - deceptively powerful in a trading-heavy deck
• Natalie Seline - it's a sad statement on power creep that I can "only" rate this Good
• Reliquary of Souls
• Skeletal Dragon
• Sethekk Veilweaver
• Dragonmaw Sentinel
• Imprisoned Homunculus
• Akama
• Bamboozle
• Ambush
• Ashtongue Slayer
• Spymistress
• Shattered Rumbler - might be wishful thinking on my part, but it looks decent on paper
• Marshspawn
• Keli'dan the Breaker
• Shadow Council - Warlock can afford to run Sacrificial Pact and other tech cards with this as a backup way to use them
• Imprisoned Scrap Imp - I thought this card was seriously overrated, but now I'm seeing that's because I was thinking of it as a Zoo card, when it's a Handlock card
• Nightshade Matron - combo with Hand of Gul'dan is amazing but unreliable
• Kael'thas Sunstrider - centerpiece of mid-tier decks
• Teron Gorefiend

Niche

• Coordinated Strike - just doesn't have the oomph of Unleash the Hounds
• Soul Cleave - only in dedicated lifesteal decks
• Inner Demon
• Blur - I think it's being underrated, but that's not saying too much
• Wrathscale Naga
• Wrathspike Brute
• Flamereaper - overrated and slow
• Hulking Overfiend
• Pit Commander
• Coilfang Warlord
• Ashtongue Battlelord
• Archspore Msshi'fn
• Ironbark
• Overgrowth - seriously overrated; Wild Growth is dead at 3 mana and this will be similar
• Imprisoned Satyr
• Bogbeam
• Nagrand Slam - probably with Kael'thas Sunstrider
• Helboar
• Apexis Smuggler
• Imprisoned Observer
• Netherwind Portal
• Lady Liadrin
• Power Infusion - maybe not in the immediate meta, but eventually will find a deck that uses it as much as paladins use Blessing of Kings
• Dragonmaw Overseer
• Apotheosis
• Renew
• Dirty Tricks
• Lady Vashj
• Boggspine Knuckles
• Torrent
• Vivid Spores
• Bogstrok Clacker
• Hand of Gul'dan
• Bloodboil Brute
• Bonechewer Raider
• Magtheridon - very good but only in very specific decks
• Mo'arg Artificer
• Dragonmaw Sky Stalker
• Rustsworn Cultist - maybe in DH token decks
• Terrorguard Escapee - good for setting up Sea Giant or similar
• Frozen Shadoweaver
• Bonechewer Brawler
• Rocket Augmerchant

Abstain (i.e. I have no idea; could be good or could be garbage)

• Soul Split
• Scrap Shot
• Starscryer
• The Dark Portal
• Corsair Cache

Meme

• Mana Burn - in the long run people will realize they're paying 2.5 mana to deny their opponents 2
• Nethrandamus
• Netherwalker
• Ysiel Windsinger
• Marsh Hydra - the kind of solid, slow card that's broken in Arena but never sees competitive Constructed play
• Beastmaster Leoroxx
• Imprisoned Felmaw
• Apexis Blast
• Font of Power
• Psychic Conjurer - only in dedicated thief priest decks
• Shadow Word: Ruin - nobody plans to let their opponent build up that big a board
• Cursed Vagrant
• The Lurker Below
• Totemic Reflection
• Enhanced Dreadlord
• Unstable Felbolt
• Warmaul Challenger
• Waste Warden - too specific a tech
• Replicat-o-tron
• Blistering Rot
• Bonechewer Vanguard
• Ruststeed Raider
• Felfin Navigator
• Overconfident Orc - it's no Tar Creeper, just hit it with a 1/1 and then value-trade it away
• Imprisoned Vilefiend
• Ethereal Augmerchant
• Soulbound Ashtongue - only for Warlock combo decks

Garbage

• Germination
• Psyche Split
• Bulwark of Azzinoth
• Scrap Golem
• Sword and Board
• Al'ar - too easy to just kill the egg
• Scrapyard Colossus - ok off of evolve effects or in Arena, though
• Infectious Sporeling
• Supreme Abyssal
• Scavenging Shivarra
• Disguised Wanderer
• Rustsworn Initiate
