Phyrexians on the Rise!

Introduction

This is a mono-black midrange deck (with a slight white splash for Path of Peril), centering around Phyrexians and utilizing Cavern of Souls to make them uncounterable. The included Phyrexians are:

• Sheoldred, the Apocalypse
• Phyrexian Fleshgorger
• Gix, Yawgmoth Praetor
• Archfiend of the Dross

The deck is only half tribal, also having some other great creatures, such as:

• Deep-Cavern Bat
• Tenacious Underdog

Format

• The deck is for the Standard format with The Lost Caverns of Ixalan being the last legal set.
• The deck is probably Tier 1.5 or Tier 2 caliber.
• The deck can be played in both Bo1 and Bo3.

This is my own brew.

New Cards

These are the new cards from The Lost Caverns of Ixalan that I am trying out:

Strategy

Main Principles

Discard Useless Cards to Liliana of the Veil

If you have useless cards in your hand, such as Duress versus decks that have only creatures or Go for the Throat versus creatureless decks, you can discard them to Liliana of the Veil.

Main Deck Synergies

Archfiend of the Dross, Bitter Triumph, Go for the Throat, and Liliana of the Veil

If it happens that the Archfiend is going out of oil counters and you are in danger of losing the game, you can kill it with Bitter Triumph, Go for the Throat, or Liliana of the Veil.

Ashiok, Wicked Manipulator and Paying Life

When Ashiok is in play, you don't need to pay life for casting Bitter Triumph, drawing cards with Gix, Yawgmoth Praetor, blitzing Tenacious Underdog. Instead, you exile cards from your library.
