Cascade (When you cast this spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.)
Instant and sorcery spells you cast from your hand have cascade.
Cast Quandrix, then chain instants and sorceries that each cascade into a free spell of lower mana value, generating massive card and tempo advantage. You want a curve of impactful spells so each cascade hits something relevant, snowballing into card draw, ramp, and a finishing burst or big swing with the trampling, flying dragon.
Every instant/sorcery becomes two-for-one (or more) via cascade, producing huge value engines
Quandrix itself is a 5+ power flyer with trample that pressures life totals while you grind
Green/blue gives premier card draw, ramp, and counterspell protection
Naturally rewards high-density spell shells with X-spells and storm-adjacent payoffs
Cascade variance can whiff or hit a weak spell at a bad time
Commander costs six mana and dies to removal, stalling the engine
Few hexproof options leave you vulnerable to targeted removal and counters
Can struggle to close before fast combo decks if cascades don't align
Doubles every instant and sorcery, doubling cascade triggers for explosive turns.
Increase spell density and lower your average mana value so cascades hit consistent payoffs rather than whiffing. Add spell-copy and extra-cascade enablers (Bonus Round, Twincast effects, Maelstrom Wanderer-style chains) plus protection like Heroic Intervention and counterspells to defend Quandrix. Tighten the mana base with fast ramp (Sol Ring, signets, Cultivate) so you reach six mana early and keep casting threats every turn.
