Next up we have mono black aggro, another formerly top deck that has fallen a little since the ban of Smuggler’s Copter and the printing of cards like The Wandering Emperor and March of Otherworldly Light. This version leverages the cheapness of Tenacious Underdog to replace the costly Rankle, Master of Pranks. The other big place you will notice the budget of this deck is in the Mutavaults, Thoughtseizes, and sideboard Kalitas, Traitor of Ghet.
The general gameplan of the budget version stays the same as the full version, your tools for executing that plan are just a little bit discounted. Getting Thoughtseizes are your top priority with this deck followed by Kalitas. Unlike with mono white humans, the Mutavaults are a nice touch to help versus the control decks of the format, but they aren’t as pressing. Similarly, Rankle is a solid reason to play this deck, but you can get away with zero Rankle and zero Mutavault for a much longer time than playing with zero Thoughtseize. Even more so than Kalitas, you will need to invest into Thoughtseize, but that is generally a solid investment, regardless of what formats you play.
This and mono red are the decks that will require the heaviest investment to get to a full build, but much like red, Thoughtseize and Eidolon are multiformat all-stars that have been important parts of their respective decks since their original printing. These are better options for long-term upgrades, but you will feel the holes in this deck if you aren’t able to scrounge up Thoughtseizes or Kalitas depending on your FNM metagame.
