- 702.41a. Entwine is a static ability of modal spells (see rule 700.2) that functions while the spell is on the stack. "Entwine [cost]" means "You may choose all modes of this spell instead of just one. If you do, you pay an additional [cost]." Using the entwine ability follows the rules for choosing modes and paying additional costs in rules 601.2b and 601.2e-g.
- 702.41b. If the entwine cost was paid, follow the text of each of the modes in the order written on the card when the spell resolves.
