This is a precon-style Jeskai deck built around Gandalf, Party Guest, and his knack for surprising the table at the worst possible moment. The story is simple: Gandalf shows up uninvited, lights off a few fireworks, and leaves everyone else scrambling to catch up. That means a spells-matter deck packed with cheap cantrips, efficient counterspells, and wizards lots of them to help Gandalf turning "just a cheap spell" into a snowballing engine of card draw and burn. It leans on Gandalf's card theme as a precon running different versions of him. I also tried to stay budget-conscious, without pricey combo pieces or fast mana beyond signets and a classic "precon" Sol Ring.
