The simple version: most modern Pokemon booster packs are dead money
These include cards such as Arceus & Dialga & Palkia-GX, Mewtwo & Mew-GX, and Dedenne-GX
But they are powerful enough to justify first-picking, and seeing them late is when you really should capitalize on them because that is a signal that nobody else is trying to employ that specific strategy, and you can therefore wheel cards that will be important for your deck
Whenever another creature dies, target opponent loses 1 life and you gain 1 life
Copying spells is always fun, and the other creatures in the deck lend themselves to getting the ball rolling, and keeping it rolling
It isnt a competitive card, but collectors chase it for the charm and the memories
