Notes & Combos

reached m1 with Fiendsmith HERO.

one of the biggest strengths of this deck is its resilience against Droll & Lock Bird. normal HERO decks are very vulnerable to Droll, but the Fiendsmith engine gives the deck ways to play around it.

To transition from HERO into Fiendsmith, you can use Moon of the Closed Heaven or Evilswarm Exciton Knight to summon Requiem.

Conversely, to transition from Fiendsmith back into HERO, you can summon Aerial Eater and send Necrom to the GY to bridge into your HERO plays.
