Jiang Yanggu, Alone

A five-mana 4/4 menace is passable, but the lone-attacker condition makes its rummage and growth too delayed for most lists; fringe top-end testing is plausible.

Could be wrong if A slower Standard or strong discard/graveyard payoff could make repeated filtering and counters a real midrange engine.

Pioneer aggro decks are too low-curved for this, while midrange has more immediate five-mana threats. Conditional combat filtering is not enough payoff.

Could be wrong if A credible red discard shell that values both looting and a growing evasive threat could create a niche home.

Five mana for a creature without immediate board impact is well below Modern's pace, and its attack trigger neither supplies a combo payoff nor protects it.

Could be wrong if An unusually efficient discard-based creature shell could exploit the trigger more effectively than expected.

Even with fast mana available, a five-mana 4/4 that needs combat before generating value is far below Legacy's required efficiency and resilience.

Could be wrong if Fast-mana creature strategies could test it as a niche discard outlet, though that would require unprovided synergy.

Sending one attacker at each opponent can produce several rummages and rapidly growing threats; it is a strong but vulnerable five-mana synergy piece.

Could be wrong if No haste, no protection, and reliance on favorable combat may leave it too slow for optimized tables.

A 4/4 menace for five is already a strong body; attacking alone turns it into a recurring filter and quickly growing evasive threat without being a bomb.

Could be wrong if Unknown speed and removal density matter greatly: fast boards punish solo attacks, while weak removal makes its growth much stronger.
