After about a year of unupped shardless PVP, I decided it would be fun to make a tier list. I've referred to decks as belonging to different tiers often enough that I figured this might be useful. Feel free to disagree or point out any decks I've missed. Every deck on the list is a deck I've either played in competitive play, had played against me in competitive play, or seen discussed by others in chat/forum. Without further ado:
theelkspeaks's unupped PVP tierlist
Brief explanation: I'm here trying to make a tier list for unupped PVP. I'm dividing decks into seven broad tiers - S, A, B, C, D, E, and F. I'm presuming shardless play for now, though I might add a separate tierlist for sharded play if the reception is high.
Counterpicking is very valuable and can win matches even with a lower tier deck against a higher tier deck. Choosing decks from the S/A/B tier decks in various mixes is generally good and reasonable play, with S and A decks occupying a higher percentage of your play but mixing in B decks still being a viable choice even without mindgating. C decks are generally good picks only if you expect a favorable matchup. Decks rated D-F are only reasonable if there are restrictions in play, such as a tournament or event rule.
Each "archetype" of deck (such as Grabbow, Light Firestall, Disquake, and so on) will only be listed once. Various mods of a given deck may be appropriate for a given situation. Mods that range far from the original deck as to become an entirely new deck might get their own mention, such as the Earthquake containing mod of Immorush sometimes called Immoquake.
Many many many of these decks can be "teched" with one or two cards to improve particular matchups, such as adding AoE if you expect a fractal based deck, or adding a useful shield or weapon.
Decks are in a very estimated order within each tier, but order within a tier is mostly "too close to call".
S tier - the devastating decks that are the backbone of competitive play: Disquake Bow, Phoenixbolt Control, Light Firestall, THE DECK, Grabbow
A tier - decks that have a drawback that can make them less reliable, but still very strong decks: Catatitans, Adrenastaves, It's A Trap, Immorush, Dream Catcher, AIR THE DECK, Monotime, Ghostmare, Psiontal, FW Vamp Daggers Bow, Vader Saders, No Flaming, Phoenixbolt Rush, AM Monoentropy, Pdialsbow, RT Shriekerquake, Toadfish Bacteria, Dragonbow, Bonebolt, Adrenavamps
B tier - decks that have good matchups and bad matchups, are often feast or famine decks: Fleshwings, Lobo Purify Trap, Bonecats, Frozen Catatians, Ragedolls, Pandebonium, Dry Nymphs, FFQ Hope, Shrieker Rush, Deja Hope, Death Smallbow, Creation of Life, BB Charge, Adrenafrogs, UG Dials, Siphonary, RT NT splash duo, Devtal, BB NT duo
C tier - use only with a good reason: Adrenascorps, Scarabtal, Shine Bright Like a Diamond, Mitoscarabs, Flying OE, Firecell, PVP Limitless Speed, Voodoo Parasite, Soul Dragon, Dissipation Dragons, Dragonflytal, Gnometal, Fractix, Dazzling Dolls, THE MONO, Life Firestall, Devquake, Growth Bow, Rustler Rush, Blessed Otys, Deflag NT splash, Drake Dim
D tier - use these decks if you either are predicting a very very hard counter or restrictions eliminate the top decks: Quinted NT UG Bow, The Dark Art, BB Catamagio, Accelerated Voodoo, BB Adrenafrogs, Dims THE DECK, Accelerated Armagios, Devtosis, BB Gravy
E tier - below the bar decks even if restrictions are in play, most likely: Fractal Red Nymphs, Lycantosis, Monolight Rush, Devgoyle, Otymono, Fractal Vu, Adrenatrice
F tier - just why would you ever play this?: PU Permission, Grabby SS, Heal/Reflect/Dim Trio Deckout
