A few underperformers are coming out and a few ways to interestingly support Living Lore are coming in.
Flux channeler has felt too niche, too hard to successfully make work and a 3 mana 2/2 is a hard sell in this environment. Slip out the back is cool but I've wanted to try something else for a while.
As I mentioned with the white changes, foundry inspector has been medium. Memory garden is a cool way to offer a strong, cheap spell once as an artifact payoff.
Into the roil and candlestick have been medium inclusions, often 23rd cards in lists. I like the idea of offering some interesting flexibility in these slots with hybrid mana. These split spells also offer a powerful thing to do with Living Lore.
