Throughout Modern’s history, very few decks have been constants of the format. The deck we’re featuring today, Affinity, is one of those decks. The artifact-based deck was certainly seen as a viable option in the format when Wizards was initially testing the format, as the colored artifact lands were included on the initial banned list. Since then, very few cards have been printed to chance the deck at all, but it still remains as a great option for every tournament.

The deck is can be thought of as having two types of cards: artifacts that cost little to no mana to play, and cards that take advantage of having a lot of artifacts in play. Memnite, Ornithopter, Vault Skirge, Mox Opal, Springleaf Drum, and Welding Jar are in the first category. Mox Opal and Springleaf Drum are particularly important, as they are positive and neutral on mana respectively, unlocking the rest of your hand very easily. Welding Jar isn’t seen often in the mainboard of these affinity decks, but this deck puts more emphasis on the high-cost cards, so it’s inclusion makes more sense here.

Arcbound Ravager, Etched Champion, Master of Etherium, Signal Pest, and Cranial Plating are in the second category. Arcbound Ravager and Cranial Plating both fulfill similar roles and slightly clash with each other. They both allow you to get extra damage out of each artifact you control. Signal Pest and Master of Etherium pump each of the cheap artifact creatures you’ve played, while Etched Champion offers less bang for your mana buck, but that bang is very hard to interact with, forcing the opponent to kill you or eventually die.

The sideboard has more cards that interact positively with the deck’s cheap artifact strategy, as well as wide-reaching hate cards that let the deck interact more with many decks in the format. Etched Champion and Ghirapur Aether Grid are both excellent against slower decks, while Ancient Grudge and Relic of Progenitus let the deck hate against artifacts and graveyard strategies respectively. Spell Pierce and Stubborn Denial in the same sideboard are interesting, as Spell Pierce is very consistent, while Stubborn Denial is not. Denial more or less forces you to have Master of Etherium, Arcbound Ravager, or Cranial Plating online for it to be used properly.

Here are the changes I would make going forward:


-1 Welding Jar

-1 Master of Etherium

+1 Memnite

+1 Galvanic Blast


-1 Dismember

-2 Stubborn Denial

+2 Spell Pierce

+1 Whipflare

This is day 155 of’s 2017 Deck of the Day column, where each day we’ll feature a different Standard, Modern, or Legacy deck that caught our eye. You can read day 154 here, where we featured a tribal Legacy deck that aims to beat down and disrupt the opponent.
