Nahiri, the Harbinger is one of these gorgeous cards, and features the lithomancer swinging lava swords at her foe
Y'shtola was chosen for Final Fantasy 14 specifically due to the character's popularity and the fact that she's a spellcaster, though ideas were floated around for a highly customizable Warrior of Light commander, but they had "pretty in-depth executions." All of these sets will be released on June 13 later this year, and given how popular the crossover is probably going to be, you might be best circling that date in your calendar three or four times
Another well-appreciated reprint, especially now that theres a different version in the alternate art
Blue has options, too, beyond High Tide
It strikes me as an excellent tool for combating battlecruiser-heavy EDH metas
Therefore, if you want either of these drops, make haste!
