pokemon 151 rare card The 10 Most Valuable Chase Cards — Joseph Writer Anderson [Water] Water Gun (10)Flavor Text Pokemon 151 looks stunning :

The heavy usage of graveyard monster effects among the top decks has resulted in Ice Dragons Prison seeing more play

It is a powerful effect that protects you from your opponents effects but it can also prevent you from benefiting from your own card effects

While we occasionally can get aggro wins by running out Valley Mightcaller on Turn 1, more often, it comes down in the late game once we have our self-bounce engine set up and quickly grows to be something like a 10/10 trample that can kill our opponent in just a couple of attacks

Both of these factors make it difficult to extract all the good from this card
