Merciless Poisoning - Toxic Deluge Price

Updated 2026-09-14

Toxic Deluge in the Merciless Poisoning Secret Lair treatment is showing consistent positive price movement across all three measured windows, with the 90-day appreciation substantially larger than the shorter-term rates, suggesting the card has been building demand over a multi-month period. Toxic Deluge is a Commander and Legacy staple board wipe: for X mana, you pay X life and give all creatures -X/-X, bypassing indestructible and regeneration in a way most board wipes cannot. That functional premium makes it irreplaceable in black-based Commander control builds. Secret Lair print windows are fixed once closed, capping supply, and the Merciless Poisoning drop's art treatment carries collector appeal beyond functional demand. The acceleration from the weekly through the 90-day window is consistent with a card in genuine multi-month appreciation rather than a short-term pop. Monitor Commander ban list decisions for Toxic Deluge as the primary downside risk.
