I look back at cards that have made a big impact in this game. A lot of the time those cards are really good but with no easy to figure out way to play them. For example, Raichu δ. The second I saw the card, I knew it was good. But I didn't know the right way to play it. Before I know, a new big deck comes around with, to my amazement, Raichu δ. I was shocked to see the strategy of the deck, but wasn't surprised a good deck came out of the card.
This card gives me the same feeling. The feeling that this card is just way too good. Sure, it has counters, but most everything does. And I look at Pidgeot. A broken card IMHO, that had many counters (including Medicham/Battle Frontier/Pidgeot δ/ etc) and yet it still plays a large part of one of the best decks (the best in some eyes) of this format.
A card can have counters, and still do well. You really have to research just how effective those counters are. If most decks (flamingspinach exaggerated with 98% of all cards but most decks are affected by it) can't run the card (Cessation Crystal), and decks tech for the tool, what do those players do when a tech'd deck faces a tech'd deck. Does the tech have multiple uses, weither or not your facing the deck you've tech'd for?
Windstorm is the obvious counter to Cessation Crystal. But just how effective is the card overall? It can discard tools and stadiums, which gives it some use against decks that don't run Cessation Crystal, but I don't think it really works as well as just running an extra stadium and trumping the opponent's stadium. Also, with very little way to search for a non-supporter trainer, just how likely are you to get one in your hand when your powers and bodies are shut off?
Decks that run Magcargo and other searching powers could go after the windstorm first, just incase the other player plays the Cessation Crystal, but what do other decks do? Cessation Crystal hurts so many decks, and many of them have no search at all. Lets look at what big decks we've seen this format that have no search that Cessation Crystal would hurt.
Mewtric
Mynx
Medicham
Flariados
JynxFett
DragTrode
LunaRock
Scrambled Eggs
All these decks have no way to search their deck for a Windstorm. Some of these decks can counter it another way, but very few can. Cessation Crystal is a hard counter to many of these decks.
In conclusion, I wouldn't laugh at this card, or think that a simple Windstorm just solves this problem. Cessation Crystal is a very powerful card, and with no clear counter to it in the future set, I could definitely see it playing a large part in a new big deck.
