The Lorcana starter decks do this already (Amber & Amethyst, Emerald & Ruby, Sapphire & Steel), but players can and should experiment with other combinations
Alright, I admit, I wanted this list to be a lot more expansive since we also have many more cards like Ultima, Town Greeter, and especially Astrologian's Planisphere (another crucial component of the new Vivi Izzet build), those that definitely had solid deck entries during the last major tournament event
Elves then got Shaman of the Pack and became a somewhat viable Bidding tribe and lastly Bloodstained Bishop turned up for the vampires giving quite a lot of scope to Bidding for the win in otherwise strong tribes
You also get new versions of Diabolic Tutor, Chord of Calling, Song of Creation, Thespian's Stage, and a Sol Ring card that makes it look like Miku is reaching for one of Sonic the Hedgehog's gold rings
The first two chapters are slow, theyre weak for their cost, and the fact you have to get through them runs the risk of you setting yourself back hard
