Gandalf, Goblins' Bane // Flameshape

Gandalf is a Wizard, so the Staff equips for only {1}. Each noncreature spell then triggers doubled prowess and Gandalf's own ability an additional time, giving Gandalf a total of +4/+4 and dealing 2 damage to each opponent.

Equipping Gandalf discounts your noncreature spells, and each one then increases Gandalf's power, making subsequent spells even cheaper while also triggering his damage ability.

Both cards reward a spell-dense deck: each noncreature spell pumps and pings with Gandalf while also turning into card selection through Uncover the Moon-Letters.

Bilbo reduces the cost of nonland spells exiled by Flameshape, and his attack ability lets you recast instants and sorceries from your graveyard to generate additional Gandalf triggers.

Plunder is a cheap noncreature spell that replaces itself and triggers Gandalf, then flashback lets the same card trigger him a second time while drawing two cards.

Tidings provides two separate Gandalf triggers through its initial cast and flashback, adding two total pings and temporary pumps while building a Goblin Army.

Both reward the same behavior — casting noncreature spells — so one spell-dense deck turns on two payoffs simultaneously.

Seek the Heart tutors Gandalf, and both casting Seek the Heart and later casting The Arkenstone count as noncreature spells, giving Gandalf separate pump-and-damage triggers from the same card.

Pinecone Strike is a cheap noncreature spell that temporarily grows Gandalf and adds his damage trigger while also removing an opposing creature.

Casting Desolation triggers Gandalf, increasing him from 2/3 to 3/4 before the sorcery resolves so he survives the 3 damage while also dealing 1 damage to each opponent.

Casting Bilbo's Gambit triggers Gandalf's noncreature-spell ability, temporarily growing him and dealing 1 damage to each opponent while Gambit disrupts their spell.

Every noncreature spell causes Gandalf to deal 1 damage to each opponent, and the Master turns each of those pings into an additional mill of one card.

Gathering of Darkness is a noncreature spell, so casting it pumps Gandalf for the turn and deals 1 damage to each opponent in addition to its recursion and amass effects.

As a noncreature spell, the Saga triggers Gandalf to grow for the turn and deal 1 damage to each opponent, while its removal chapter helps Gandalf attack safely.

Radagast is another Wizard, so controlling him keeps the two cards banked by Flameshape playable even if Gandalf has not yet been cast or has been removed.

Gandalf, Wandering Wizard satisfies Flameshape's Wizard requirement, preserving access to its exiled cards when Goblins' Bane is unavailable.

Gandalf, Spark Starter is a Wizard that can unlock the cards exiled by Flameshape if Goblins' Bane has been removed or cannot be deployed.

Casting Thranduil's Decree triggers Gandalf's noncreature-spell ability, dealing 1 damage to each opponent and potentially giving Gandalf +1/+1 during combat while Decree stops and steals a spell.

Inside Information triggers Gandalf as a noncreature spell, and stolen noncreature spells can produce additional temporary power boosts and opponent damage during the same turn.

Casting the Saga triggers Gandalf's noncreature-spell ability, temporarily increasing his power and dealing an additional point of damage while the Saga continues generating value.

Casting Uneasy Partings triggers Gandalf's noncreature-spell ability, temporarily increasing his size and dealing 1 damage to each opponent while the bounce spell supplies interaction.
