Enervate, meet Arc Lightning as an instant

I personally really like Thoughtseize because it always feels great to be in control and trade your one-mana spell against some big threat of your counterpart

Looking back now, 5 mana is an awful lot to ask of an enchantment that doesnt do anything when it enters the battlefield, but if allowed to sit on the battlefield after a board wipe or a couple turns of play from an Aristocrats strategy (decks that derive value from sacrificing creatures), Black Market can quickly generate game-winning amounts of black mana

So he gets a fair amount of protection from that

You can also counter any Commander for just a single mana since it's cast from the Command Zone
