buy mtg commander decks Masters CMM Commander This Red Wizards of The Coast Magic:

You see potential value in some cards included in a Starter Deck, making it cheaper to buy rather than purchasing each card individually or hoping to pull them from Booster Packs

Whenever an opponent casts a spell, Kaervek the Merciless deals damage equal to that spells mana value to any target

Catching Combo and Aggro With Their Pants Down The ability to counter without spending mana meant Force of Will could reliably stop turn 1-3 combo and aggro decks in their tracks, even when tapped out

I don't think he's my cup of tea, but he's gotta be good if the niche appeals to you

I clearly wasnt alone in this line of thinking, because Black Market and Pawn of Ulamog saw an absolute ton of play during Commanders early years, and the former was actually a chase card for a while since its only printing was in Mercadian Masques prior to the release of Commander 2015
