If you look at our level-up creatures, you'll see that almost all of them start off underpowered based on their cost, before eventually becoming good or even great, assuming we can dump a bunch of mana into leveling them up (without our opponent killing them in response)
Tribal and Kindred Decks Kindred / Typal decks focus on a Creature type and their respective payoffs: Elves, Goblins, Zombies, Merfolk, Dragons, Vampires, Cats, Slivers, and so on
