Kuldotha Phoenix

The recursive Phoenix tied to a metal subtheme, and the gating on its return is the discipline that makes the rate work. A 4/4 flier with haste for five is a fair-but-respectable body; the upside is the reanimation, and the card hangs two locks on it at once. It only fires during your upkeep, so it cannot ambush a combat step or answer something at instant speed: the return is restricted to a window you control rather than one you exploit. And it demands metalcraft, so you have to actually be the artifact deck rather than splash for a recurring threat. The haste is what makes the wait worth it: because the body comes back swinging on the same upkeep it returns, the buys an immediate clock rather than a creature that sits a turn before it matters. Stack those constraints and the card stops being a free engine and becomes a payoff: the reward for committing to a critical mass of artifacts is a flier that keeps coming back, but only on rails you build the rest of your deck to support. That is the through-line of the whole Phoenix lineage, from the original onward: a body that resists removal in exchange for resisting easy inclusion. Here the resistance is artifact density, which makes the recursion a referendum on your deck's commitment rather than a generically abusable loop.
