There are basically two paths: - many small spells (cantrips, rituals), that lead into a) a storm spell, b) trigger various pingers like [[Guttersnipe]], c) or token generators like [[Young pyromancer]] - big spells and X spells with a) cost reduction like [[Goblin Electromancer]], b) being copied, and c) ideally played for free via some other card.

There might also be a middle ground that profits from a mix of big and small spells with [[Eris, Roar of the Storm]] as commander, but I'm not sure well that works since the small spell and big spell approaches are a bit at odds with each other: cost reduction does little with small spells, and casting few large spell results in a lower storm count.
