What are the weaknesses and retreat cost of this Snivy card

Hiu ng gc (EN): 1 "Nordic Alfar" Tuner + 2+ non-Tuner monsters Once per turn, when your opponent activates a Spell/Trap Card during your Battle Phase (Quick Effect): You can negate the activation, and if you do, destroy it

At minimum you'll be paying 3 mana to save your commander, draw and discard a card which feels like a fair deal for its mana cost and I can see many Dimir graveyard, discard, reanimator or Izzet/Grixis wheel deck slot this card for its instant speed potential

None of these are particularly powerful on their own making this card not super impactful in my opinion
