Giant Growth (Serial Numbered) Price

Updated 2026-07-03

Giant Growth (Serial Numbered) is a Secret Lair promo variant of one of Magic: The Gathering's oldest instants, issued with an individualized serial number that places it among the most supply-constrained treatments in the modern era. Serial-numbered printings attract collectors who value documented scarcity alongside gameplay history, and Giant Growth's tenure in Magic since the Alpha set gives this version a layered collector appeal that generic print runs cannot replicate. Price data shows a divergence between the 30-day and 7-day windows: the medium-term frame reflects substantial appreciation, while the short-term reading has gone flat. That pattern is common when a sharp move exhausts near-term buyers and the market pauses for consolidation. Whether the 30-day gain holds or partially retraces will depend on broader demand for serial-numbered Secret Lair promos, a collector-focused segment where scarcity and gameplay relevance both contribute to pricing.
