For decks aiming to maintain a steady crime spree turn after turn, these sorts of enablers will pay for themselves but you need a fairly high density of high-impact payoffs to justify them
King Darien is a little pricey for an aggro deck, sitting at five mana for a relatively small creature, but with enough mana, it can snowball into a huge creature
Somehow, its gone 30 years without a reprint, which is wild for any card
And I normally don't factor this in, but the new art on cards in this deck is outstanding
Its also solid just to cast it and then flash it back, though Id definitely try to include ways to 2-for-1 with it
While it may often be overloaded to deal with all artifacts you dont control, its one of the few removal spells that can punish a Sol Ring start on turn one
