Fat chance, fairy is too easy to counter. dunames counter with 4 star ladybug, mauseleum and spells counter with dark paladin or magic jammer/drain. Skelengel counter with baou sword. Or better yet, use some cards to wreck their hand when see a fairy drawn.
OK I agree that this deck is not good but the reasons you gave are completely 🔥 lol. 4* Ladybug and Power of Dark aren't popular atm. Dark Paladin/Magic Drain are decent but rarely used, and no one ever runs Baou Sword.
