It is most likely going to be helpful to know what each colour has as its group for this block :p
WHITE: mechs and cat warriors (Enchants)
GREEN: Elves and leprechauns if you want Alex ( tokens)
RED: Goblins And Beasts (burn)
BLUE: humans and merfolk (+1 +1 Counters)
BlACK: demons and evil faeries and pixies
Multi colored has two main sets, the foulskin creatures who rely on luck (coin flipping) to get a bonus or a downside. and the second set is the dragons and draco servants who tend to be game changers.
