Deck Primer / Description

The deck tries to play like a proper tavern brawler - it does things all the time, has access to a lot of interaction, but nothing is really dangerous or big. It just deploys some instant/sorcery payoffs and then cantrips and bounces creatures around, until it slowly wears the opponents down.

Gale, Waterdeep Prodigy provides access to massive card advantage, that is not too apparent on first sight. It is very easy to underestimate the deck - having Gale out and just 3 cards in hand can actually translate to 5 spells being cast.. if no additional draw is involved and the graveyard is empty. Also, having sorcery cards in the graveyard means that you can play them at instant speed by playing some cheap instant spell along with it.

There are 20+ interactive spells in the deck and Gale's ability makes most of them re-usable. This leaves you with maybe 40+ opportunities for interaction - much more than in other average EDH decks. So don't hesitate and use them quite freely to slow your opponents down.

Vast majority of the cards are very budget friendly and if you replace Urabrask, Ghyrson Starn, Kelermorph and Exalted Flamer of Tzeentch with cheaper options, you can cut the price significantly.
When editing the deck, keep in mind that you can't really play counterspells from the graveyard, so you don't want to play too much of them.

I have also experimented with Goblin Electromancer and other creatures giving discount to instant and sorceries, but they don't seem to be worth it - many spells don't need colorless mana and even though the discounts are sometimes very handy, mana rocks that give colored mana (or even uncolored that can be used for anything) are much better in the early-to-midgame.

I have also tried playing more mana artifacts, but the need to have access to instant, sorceries and payoffs is already a big requirement and less of those resulted in less consistency. For this reason instead of more mana rocks the average cost of spells is kept low instead.
