Prismari Command is basically never a dead card, and thats what you want
However, this almost wants to pick up its own counters, because the bigger it is, the more likely it is to trigger again on future turns
It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or any Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, or so on
The Final Fantasy TCG also has a lot to love for fans of the video game series
The alt-art Charizard VSTAR and Mewtwo VSTAR show the Generation 1 Pokmon dueling, each one from a different perspective of the same battle
Its also an opportunity to play Eldrazi in commander without having to make your deck 100% colorless
