Anrakyr the Traveller

Attack triggers usually reward the swing itself: a card drawn, a token made, a point of damage pushed through. This one reroutes the entire artifact-casting economy through the declare-attackers step. Send it in, and any artifact spell in your hand or graveyard becomes castable for life equal to its mana value, turning combat into a second main phase whose currency is life rather than mana. The design consequence lives in that mana-value clause: a five-value artifact costs five life, a fifteen-value one costs fifteen, so the payment scales exactly with what you deploy. Life is the ceiling, not mana, which is a different resource to budget and one most decks have more slack in than they think. The graveyard half is what gives the ability teeth beyond a mana-rock deployment engine: recursion for artifacts is normally a dedicated slot, and here it rides on a creature that only has to be declared as an attacker to fire. That is the constraint worth naming: the trigger keys off the attack, not connection, so a chump block does not stop it, but the ability still demands a live 4/4 willing and able to swing each turn, which opponents can answer by killing the body before combat. It reads as a lord in name and flavor, but the mechanical identity is closer to a repeatable, life-priced free-cast outlet stapled to a body: the decks that want it are the ones loading up on expensive artifacts to be paid for in blood instead of mana.
