The on-death face damage effectively reduces their clock by a turn, so even if your trick only blocks the first attempt to remove the Hero, the combination of extra +1/+1 counters and an extra swing in combat (almost certainly unblocked since they wasted the last turns mana) should bring them low enough to finish off with haste and burn spells
If only every hand could have three pieces of Power in it
Counterspells are good, and Spell Snare specifically is one of the best cards against Storm
The limitation comes in with ACE SPEC, Prism Star, and Pokmon Star cards, where only one will transfer over
The card has a low retreat cost, two great moves, one that helps evolve your Pokemon, and the other than does damage and heals damage at the same time, so again, if you're building a Fairy type deck, I would highly recommend playing this card
