Question:

Why should types that are original Magic IP like Viashino be folded into generic types like Lizard, but the same is not true for UB types like Astartes or Cyberman? Is there no value to building resonance for Magic's IP?

Answer:

The Viashino are still flavorfully Viashino. It’s still a unique race of creatures. That’s what they’re called. All we’re changing is their creature type. We’ve decided to be consistent with how we’re labeling animal humanoids such that they and their animal equivalent are connected typally.

A sad day, as I love the Magic unique types.

And while Loxodon isn't a typed type... Viashino, Homarid, Cephalid... were.
Are all my homarids lobsters now? Cephalid squids or octopodes?

Why not roll Skeletons and zombies into undead? /oldman

Edit: but it does make them match Leonin and Loxodon. So consistent, I guess.
