Proliferate X times. (To proliferate, choose any number of permanents and/or players, then give each another counter of each kind already there.)

Character Background
Expansion Algorithm is a cleanly designed blue sorcery that rewards planning, board awareness, and inevitability, making it especially strong in control and value shells that can afford a big X turn. Each cast turns every existing counter into a snowball: loyalty climbs faster, +1/+1 counters widen combat threats, charge counters accelerate artifacts, and poison or energy strategies can suddenly jump from manageable to decisive. Because it costs {X}{U}{U}, it wants a deck that can survive early and then convert excess mana into a burst of advantage, often after a sweeper or during a protected end step. It pairs particularly well with walkers, The Ozolith-style counter retention, and anything that enters with useful counters already in play. In Commander, it becomes nastier with untap or copy effects, since proliferating multiple times can convert one stable board into a runaway engine. The card is less about immediate tempo and more about turning a developed position into an overwhelming one.
