2 rulings from Wizards of the Coast
- 7 August 2020The last ability of Jhoira's Familiar doesn't reduce its own cost while you're casting it.
- 7 August 2020A spell is historic if it has the legendary supertype, the artifact card type, or the Saga enchantment subtype. Having two of those qualities doesn't make a spell more historic than another or provide an additional bonus—a spell either is historic or it isn't.
