Morph isnt particularly strong and doesnt quest for much, but it's cheap, only costing two ink, and since it can come down early, you can set up some great shift plays just a few turns later
To play this card, I'd say you need to be into the prowess realm, or have specific synergies with enchantments/artifacts
Since Inti casts from exile we also can run some powerful exile support synergies: Party Thrasher ramps out noncreature spells, Iraxxa, Empress of Mars generates creatures, Unstable Amulet burns out opponents, but my favorite is Impending Flux which is a one-sided wipe that doubles as a way to finish off opponents
Although very powerful effects on the whole they generally don't have much baring on the cards overall viability
You can obtain the Azumarill (2-Diamonds rarity) card by opening Wisdom of Sea and Sky: Ho-Oh from Wisdom of Sea and Sky set
