My work on limit breaks ended up influencing the exhaust mechanic in Aetherdrift that, despite coming out first, I worked on after handing off the vision design for this set
My main gripes with Prismari Artistry are that the mana base feels a little high, likely to make the most of Rootha's ability, so I've found myself almost downgrading the deck with some cheaper spells to stay relevant in the game during earlier turns
Because you almost always sacrifice as part of a cost rather than on resolution of the effect, its immensely difficult to contest the important part of the mechanic on the stack
Another Limited card, as there are just too many strong fives available in Constructed
Its other printings are still only around a dollar
Some abilities restrict you to sorcery speed, like Tarrian's Journal, but outlets like Goblin Bombardment that dont limit you can be activated whenever you have priority
