You may cast sorcery spells as though they had flash.
Whenever the Ring tempts you, if you chose a creature other than Gandalf as your Ring-bearer, draw a card.
Hold up mana and react: Gandalf lets you cast everything—including sorceries—at instant speed, so you play a flash-control game, deploying threats and answers on opponents' turns while drawing extra cards each time the Ring tempts you (just keep a cheap token or different creature as Ring-bearer). You win by leveraging flash flexibility, card advantage, and big interactive blue payoffs.
Add fast mana (Sol Ring, Mana Crystals, Mana Vault) and the best counterspells (Mana Drain, Force of Will, Fierce Guardianship) to make your flash interaction free and proactive. Tighten the deck around one or two compact combos—Isochron Scepter + Dramatic Reversal feeding Aetherflux Reservoir, or Thassa's Oracle plus a self-mill enabler—and lean on tutors like Mystical Tutor and Personal Tutor to find them. Cut purely reactive filler for proactive card advantage like Rhystic Study and Mystic Remora so you out-resource the table.
