Lethal Golgari Budget (Pioneer) [Revisão 23]

The idea of the game is to try to take control of the board quickly thanks to the many removals.
Thanks to removal and Chevill, Bane of Monsters you can earn life and draw.
Westgate Regent puts a lot of pressure and can do a lot of damage.
Deathtouch creature is great for controlling the board and helping you use Vraska, Golgari Queen last ability that give you another win condition. (Remember that you don't have to sacrifice a permanent to get Vraska's +2, but you can sacrifice the token of Prosperous Innkeeper or an useless land in case)
Prosperous Innkeeper helps you with gaining life and treasure token.
Malakir Rebirth helps you with mana and can be useful for saving creatures, plus combo with Prosperous Innkeeper.
Llanowar Elves helps you with mana.
Fynn, the Fangbearer give you another win condition with the poison counter.
Duress so you can see enemy hands and remove annoying non creature non land card.

Sideboard
Languish for mass removal
Weathered Runestone against deck with a lot of graveyard and library interaction, I prefer this than Grafdigger's Cage because can stop also Greasefang, Okiba Boss ability
Gaea's Blessing against mill
Liquidate can help against some aggro
Return to Nature if enemy has some annoying artifact or enchantment
Necromentia against enemy win condition card
