Because the set isn't defined by a single world, it has the ability to add cards to themes before and after it
Notably, its ability doesn't just trigger from instants and sorceries, though they are probably the best option to build around for a Blanka deck
Theres definitely an eerie vibe with the card, especially when you take a closer look at the background and see at least three other people dissolving into nothing in the background
For example, you may find a card that's black, green, and blue as the black card and still find a green card and a blue card
Competitively, Ogerpons Teal Dance ability is its greatest asset, allowing players to attach a Grass energy from their hand and draw a card in the same turn
