Pinnacle Affinity is the clearest home, but five mana, BB, and no immediate effect are major costs for a deck that usually needs faster payoff cards.

Could be wrong if If its mana can reliably cast BB, a wide artifact-creature board could make the multiplayer-style drain effect a meaningful race tool.

Even with fast mana available, BB and a five-mana delayed combat payoff are poor fits for Legacy's efficient threats and interaction.

Could be wrong if A fast artifact-stompy shell with reliable black mana could exploit the attack triggers more effectively than expected.

In artifact-token swarms, each attacker drains every opponent and scales strongly in multiplayer, but this five-mana creature supplies neither tokens nor immediate value.

Could be wrong if Its payoff may be too slow and removable for optimized tables, or artifact-token density may make it a stronger finisher than expected.

Its baseline is a serviceable 3/4 that improves races, while additional artifact attackers turn it into a strong synergy payoff; support and speed are unknown.

Could be wrong if Artifact creatures may be too sparse for the attack lord text to matter, leaving an underpowered five-drop.
