Its proven great in my Legacy deck, but Ive slotted it into many EDH decks as well
Seeing as each player starts with 40 life in Commander, this artifact will equip at maximum strength, assuming you aren't facing a hyper-aggressive deck that happened to target you

Vindicate allows decks to contain free land destruction along with artifact and enchantment removal without having to devote any space to such utility or ever risk having their creature removal or anything else stuck in their hand
It plays in the rare Rakdos spellslinger space, and does some obscene stuff if left unchecked
Pitiless Carnage This slot used to be Reprocess, but Pitiless Carnage is a strict upgrade on effect alone, let alone the plot alternative
