mermaid yugioh deck Yu-Gi-Oh! Rush Duel/Deck Modification Pack - Dynamic Eternal Live!!]Enguarding RD/KP05-JP004 Normal | Buy from TCG Republic Effect Monster Rarity Sky Striker Deck Shizuku Kagari

To keep with my last articles theme of good cards in both formats, Ill coincidentally be going over one of the defining cards of Standard

Your opponent doesn't play anything meaningful on their turn and simply says "Pass." You say, "During your post-combat Main Phase, activate my Insolent Neonate." You discard the Imp, dredge 5, and reveal two Prized Amalgams and a Narcomoeba

Unlike with regular attacks, NOTHING can stop a monster effect

Ultimately, its playability would depend on the deck's overall synergy and strategy

To start off you get a 3/1 creature for two mana which can be quite good in an aggressive red/white deck
