We now have the Simic guild’s keyword spoiled: Evolve.
It’s a nice twist on the old one: Graft (from Dissension). This card rewards us for playing bigger and bigger creatures. Also, you can combine it with other things like Mikaeus, the Lunarch’s ability or things like Scavenge from the Golgari guild to get some nice card drawing.
It looks a tad on the week side, but most of the set is yet to be spoiled. Who knows what the future has in store for Fathom Mage?
