velok

I play Gauntlet exclusively and keep stats on every deck I make tiering them by their ability to get to the boss and ability to beat the boss (full clear). Lots of my deck have 95% in both, but only 5 out of 100s of my decks have never lost in over 15+ full clears in gauntlet, and here is one of them! It's not that hard to make an OP gauntlet deck, the challenge is making them fun.

Overview

I usually make a deck out of every promo, so here is the one for Velok, the Witherflame.

Velok allows you to full clear through aegis and regen, and some of your creatures are immune to it (Direwood Pack and Soul Collector). It's also fun to try to calculate the clears with the order and the corrupted units.

Usually you just keep Velok, the Witherflame in hand until you need to clear. You can also play it and sac it for draw since you can easily bring it back with Voprex's Choice or Haunting Scream.

There's one Centipede Keeper because the card is good in the deck, but I couldn't fit it. You can get rid of it and add a Twisted Farmer. Twisted Farmer is used for sac fodder, Direwood Pack building and for the Kato, Arena Herald condition.

Mulligan

Looking for Kato, Arena Herald, Grenadin Drone, Two-Face, Unfamiliar Interloper

Market

Soul Collector can be used with a Velok clear. Even at 1/1 the soul collector won't die.
Haunting Scream can be used to full clear with a velok in the void for only 3, or it can get Kato, Arena Herald to create two 8/8s.

Influence

You want 1 of each initially, then 3 purple for Velok, the Witherflame, then 4 red for Granite Waystone

Alternatives

All other potential cards I thought of that fit the theme of the deck for either market or maindeck are in the Sideboard
