Cards are split up by rarity in Pokmon TCG Pocket, separated by Diamonds, Stars, and a Gold crown
I think random stuff like this could be in play, but if you look at the Zombies stuff that went up, it was $5 cards going to $10 rather than $0.75 cards going to $2, and there arent a ton of $5 spirits
Reanimator As the name suggests, reanimator decks rely on graveyard synergies and are built around bringing one (or a lot of) creatures to the battlefield
You can also participate in "breaks," where you buy a spot and get all the cards from a specific type or team pulled from a box opening
Number 6 It surprises me how much I don't see this card at tables
In Constructed, finding lands and sifting through your powerful cards to find the right tool is desirable
