That means that no matter who your commander is, you can play it in your deck
But how does the set play
Creatures (23) 2 Verdurous Gearhulk 4 Metallic Mimic 3 Rishkar, Peema Renegade 2 Herald of Secret Streams 4 Kumena's Speaker 4 Merfolk Branchwalker 4 River Sneak Lands (23) Spells (12) Okay, so I guess Metallic Mimic as our tribal lord is sort of working with the +1/+1 counter theme except, none of the +1/+1 counter cards are particularly exciting
A cheap creature with an indestructible counter can protect a beefier one, while you can mix different level-up creatures with different costs
Kargan himself is a fine example of a level up dork, he is a perfectly acceptable beater when you first make him and invest no further mana into him
