One ruling from Wizards of the Coast
- 5 August 2026Chromatic Sphere’s ability is not a mana ability. Players can respond to it, and it can’t be activated in the middle of paying for a cost. A recent update to rule 605.1a has made any abilities that move cards to or from libraries no longer mana abilities.
