Flock Impostor copies a creature on entry and keeps copying whenever it attacks — consistent, repeatable impersonation stapled to a combat trigger. Thurid, Mare of Destiny decks run it because that kind of on-attack value aligns directly with how the deck wants to spend its turns.

Thurid, Mare of Destiny
Thurid, Mare of Destiny rewards attacking, and Flock Impostor turns every attack step into a fresh copy of your best creature — the two cards share an axis so cleanly that inclusion at 17% of Thurid builds undersells how naturally they fit together.

In Commander, Flock Impostor earns its slot in any deck that attacks regularly — it scales with the best creature on board, which in a four-player game is often something extraordinary. Constructed formats are harder to crack: Pioneer, Modern, and Legacy all have faster, more reliable payoffs, and a three-mana creature that needs to attack before it copies anything is slow by those standards. Standard is the one non-Commander format where Flock Impostor has a real shot, since the power ceiling is lower and mid-game board presence matters more. Legacy and Vintage are non-starters — the card simply isn't fast enough to matter.
