Ulalek, Fused Atrocity

Every payoff in the Eldrazi shell has asked the same question in a slightly different way: how do you make the wait for a fifteen-mana Emrakul, the Aeons Torn worth it? This one answers by refusing to stop at the spell. Cast an Eldrazi, pay two colorless, and the copy clause reaches across the stack to duplicate every spell you control alongside all your other activated and triggered abilities in the same window. That second half is the real engine. The Eldrazi tribe is stuffed with cast triggers: the "when you cast" draw and mill riders on the bigger monsters, the value stapled to their spells, the etched-in reward for spending colorless mana. Those triggers go on the stack when you cast, which is exactly when the payment lets you fork them. The devoid frame and the five-symbol colorless-or-hybrid cost lock it to a dedicated shell: it does nothing for a deck that is not already casting the tribe's monsters, and the payment only means something once your stack is already crowded with Eldrazi triggers. The 2/5 body confirms the intent; nobody wins by attacking with this. The design shifts how the Eldrazi get paid off. The old reward was a single overwhelming top-end threat you cast once. This one rewards density, turning every subsequent Eldrazi into a multiplier on everything already resolving, scaling with how deep you commit to the tribe rather than how big your biggest spell is.
