Standard Fynn's Fangs by LegenVD
Today’s Standard budget deck requires only 19 common, 8 uncommon and 8 rare wildcards if you just have the starter decks unlocked. The deck is built around deathtouch and it’s quite capable of winning the game with poison counters thanks to Fynn, the Fangbearer.
On the first few turns, you want to deploy your 1/1 deathtouch creatures and cast sorceries like Adventurous Impulse and Adventure Awaits to find Fynn if you don’t have one in hand already. Ideally, Fynn is deployed once you already have multiple deathtouch creatures in play so that they can attack and poison the opponent right away.
Your creatures also get to take full advantage of the “bite” removal spells like Rabid Bite and the instant speed Ram Through, which can kill any opposing creature when paired with deathtouch. Hooded Blightfang gives the deck an alternate win condition besides Fynn and can quickly end a game, especially when you draw multiple copies. The other rare wildcards are spent on Darkbore Pathway, which can be useful for many other decks and provide useful mana fixing for a deck that really needs to curve out.
This build does play with Typhoid Rats, which is currently only legal in the best-of-one format as an Arena exclusive. There are no great replacements at one mana, but Mire Triton and Vengeful Reaper are both solid inclusions.
Against decks that’ll be packing a lot of removal, after sideboard you can bring in ways to recur creatures from the graveyard like Lurrus of the Dream-Den or Call of the Death-Dweller. Duress can also be used to good effect as a cheap disruptive spell that can potentially take away a key sweeper.
It could also be a good idea to pack a few answers for opposing copies of Polukranos, Unchained, as its damage prevention lines up especially well against deathtouch creatures. Feed the Swarm is probably the most efficient tool for the job that also has a few other applications. Nighthawk Scavenger can additionally be a useful tool against opposing aggro decks that can’t easily remove it.
The main card worth adding to the deck is Chevill, Bane of Monsters. He lines up especially well against creature decks like Gruul Adventures, where it survives a Stomp from Bonecrusher Giant and there are plenty of bounties to claim with your removal spells. You could also freeroll Jegantha, the Wellspring in the companion slot. Alternatively, you can consider running Lurrus as your companion by taking out Hooded Blightfang. Combined with main deck copies Call of the Death-Dweller, it can give your deck a better late game plan.
