At the Store Championship it was energy deck after energy deck with Sultai being the main offender. I quickly realized that I didn't have quite enough removal to deal with their numerous 2 drops. So I decided to add another copy of
Fatal Push and
Harnessed Lightning as well as a copy of
Essence Extraction. I also wanted another sweeper in the main deck so in comes
Hour of Devastation as while I do like
Bontu's Last Reckoning it can bite you in the butt. The 5 damage from
Hour of Devastation is usually enough to clear the board with the added benefit of killing
Hazoret the Fervent and Planeswalkers.
Chandra, Torch of Defiance has been swapped with
Vraska's Contempt from the sideboard to provide another removal tool. While
Magma Spray is great against mono black and has some use against GPG decks, I think the life gain from
Essence Extraction is more useful against Ramunap Red which is the more prevalent deck.
Glint-Sleeve Siphoner is an all-star as I quickly learned at the store championship so I wanted to find a way to include her. I considered putting her in the main but I actually think she's better suited in the sideboard in this deck to swap in game 2 as many opponents will side out their early removal allowing her to stick around. Finally, I also added another copy of
Abrade to the sideboard for artifact decks such as GPG.
