Icingdeath, Frost Tyrant

A four-mana flier that pays you again when it dies, and the payment is the interesting part: the death trigger hands you a legendary Equipment token that carries the tyrant's threat forward on any creature you like. The dragon dies, the sword remains. That token, Icingdeath, Frost Tongue, does the tapping work in combat, freezing a blocker every time the equipped creature swings, so removing the dragon does not close the offensive window it opened; it relocates the pressure onto a cheaper body and asks the opponent to deal with the problem twice. It resolves a familiar white puzzle (a card should be hard to answer with a single removal spell) through flavor rather than a static resilience keyword: the artifact half is a permanent that survives sweepers aimed at creatures and reattaches after each host dies. The two halves never share the battlefield, and that sequencing is the point. The front half is a straightforward evasive beater; the back half is a pure combat-warping tool with no body of its own. Neither is redundant with the other, because you only ever hold one at a time, and the transition is triggered by the very removal an opponent uses to answer the first. It is a legend built to be traded, not protected: you are meant to spend the dragon and keep the blade.
