Prismatic Dragonstorm is a five-color Commander ramp/midrange Dragon tribal deck built around Ramos, Dragon Engine and a high-color-value spell package. Its main plan is to ramp hard, fix all five colors, then start dropping big Dragons and value creatures that snowball the board.
Key synergies:
Ramos, Dragon Engine rewards multicolored spells by generating huge bursts of mana.
Dragon payoffs like Dragon Tempest, Scourge of Valkas, Lathliss, Dragon Queen, Utvara Hellkite, and Dragon's Hoard turn each Dragon into damage, tokens, haste, or card advantage.
Extra-combat threats like Aurelia, the Warleader and Scourge of the Throne help close games quickly once the board is established.
A strong ramp/fixing package with mana rocks, land ramp, and Dragonkind orbs helps cast expensive top-end threats consistently.
It wins by overwhelming opponents with large flying attackers, often dealing extra damage through Dragon ETB/attack synergies and explosive combat steps.
