With the potential to deal damage to multiple opposing characters when first played, and the ability to toss on some extra offense when banishing a card, it's easy for Tinker Bell to take care of multiple enemies at once
Snorlax, Garchomp Ex, Leafeon Ex, Crobat, Raichu, Carnivine, Irida, Barry, and then Pokemon TCG Pocket 's Arceus Ex itself are all either very valuable now, or at least tend to pop in and out of meta decks consistently
Sure, you can easily whiff and hit lands or spells that aren't useful (Counterspell, Comet Storm, etc.) but generally speaking this ability is going to be well worth using
The biggest downside to the deck is its vulnerability to board wipes
It is up to players to solve the mystery of their origin, making Whispers in the Well feel like a frightfully fun set to dive into this time of year
