pokemon water energy cards - 93/108 Reverse Holo Shield Base Set Singles Water Energy (GEN 77) Generations

All these options are significantly less expensive than buying Cyclonic Rift, and they come with various advantages: they're cheaper to cast, they deal with permanents permanently, and as artifacts they can be tutored up easier with cards like Whir of Invention

The latter includes cards like Be'lakor, the Dark Master, Pantlaza, Sun-Favored, and The First Sliver

If their deck utilizes the graveyard, then Faithless Looting is even better and has no downside at all

Built to Last: With 5mm thick crystal clear acrylic walls, this case is made to protect and showcase your collection for years to come no yellowing, no clouding, stays clear
