Jaya may be incentivizing players to run spell-slinger, which is the dominant deck in the cube as it stands, but Zariel was unfortunately never worth it (cool art tho).
Although I like Torens and Wayfaring Temple, especially in the Bant tokens deck, I'm excited for Ajani, Sleeper Agent. It sucks that its -3 is the +1 of Ajani Mentor of Heroes, but I think +1/+1 synergies are strong throughout the cube.
