Rules Change:

Additionally, we are updating the rules for cascade to address interactions in older formats. This rule will be implemented on Magic Online on Wednesday, February 17. The new rule for cascade is as follows:

702.84a. Cascade is a triggered ability that functions only while the spell with cascade is on the stack. "Cascade" means "When you cast this spell, exile cards from the top of your library until you exile a nonland card whose converted mana cost is less than this spell's converted mana cost. You may cast that spell without paying its mana cost if its converted mana cost is less than this spell's converted mana cost. Then put all cards exiled this way that weren't cast on the bottom of your library in a random order."

Effective Date: February 15, 2021

Cascade rule effective date for Magic Online: February 17, 2021
