Rakdos Headliner

Echo has always been a devil's bargain: pay twice for a body you already spent mana to cast, or watch it leave. Rakdos Headliner reframes that bargain by pricing its second payment not in mana but in a card. A 3/3 with haste for two mana that swings the turn it lands is already ahead of curve; the echo clause is the interest rate on that loan, and here you settle it by pitching a card rather than untapping lands. That distinction is the whole reason the design works in a graveyard-hungry shell. Discarding to a cost is only a downside when the discarded card is dead weight; when your deck wants cards in the yard (a reanimation target, a flashback spell, something with escape), the echo payment stops being a tax and becomes a delivery mechanism. The card asks whether you would rather keep a fast, evasion-free beater or feed your graveyard while keeping the beater anyway. Devils in this color pair tend to trade a piece of themselves for reach; this one trades a card from hand for a permanent that stays. The friction lives entirely in that upkeep window: forget to pay and the 3/3 sacrifices itself, so the aggressive body and the graveyard engine are welded to the same clock. It is a rare instance of echo used not as a drawback to survive but as a resource conversion you want to trigger.
