J'suis Vitkor'ieux pour 20$usd (w/ENG guide)

20$ deck humbling them 200$ decks.

Mulligan:
Look for;
Poro > Honest Broker ,  (Jayce + Vanguard armory) > B.F. Sword > Cull the weak

Poro and Broker to get a gold token early. Sacrifice the Token with Jayce to play Armory.

B.F. is just a big boost overall for every token units, it'll stay all game and make them oppressive.
Cull is just nasty in this deck. sacrifice a 1cost token after conquer and kill a threat.. nasty.

Battlefield:
1st round: Treasure Hoard works insanely fine with the Jayce/Armory combo. no need to look for a Poro or Broker anymore and it doesn't advantage a lot of decks your opponent might play so... good 1st pick.

2nd round: Forbidding waste is kinda sick for your very weak units. kind of an unofficial ''+2might'' for them so you don't need to Swarm in to conquer the battlefield.

3rd round: Trifarian War Camp is classic for swarm decks. I don't think you need any explanaition on why it's good, but why not over Forbidding Waste? because it helps your opponent a bit more than FW does.

Decks' combos:
Gold token spawner(Poro/broker/Wages of pain/Treasure hoard) + Jayce sacrificing the token into Vanguard Armory.
Belows Breath + Imperial Decree to instakill 3 units.
Shadow's call + Cull the weak/Hidden blade/Imperial Decree to draw 2 + adding value to the now temporary unit.
Fanfare + Armory to draw 3 for 3cost.
Imperial Decree + Swarming recruits

Sideboard:
+3 Deathgrip v.s. control decks

Turn to Dust v.s. Gears (Aurora, Hook, Jayce, etc.)

Dredge Up v.s. rush decks to get your combos as quickly as possible.

2nd Singularity for mid range decks.
