Rain of Filth (Rainbow Foil) Price

Updated 2026-08-25

Rain of Filth in its Rainbow Foil treatment from the Secret Lair Drop Series trades at $48.53. The 30-day gain of 2.99% and the 90-day gain of 2.06% track closely, suggesting consistent accumulation at a measured pace; the past week added another 1.83%. Rain of Filth is a Reserved List spell that converts lands into black mana for a single turn, providing a ritual effect with a significant sacrifice cost. The Rainbow Foil Secret Lair treatment commands a collector premium above standard copies, attracting buyers who value the visual presentation alongside the functional Reserved List scarcity. The measured price action indicates a balanced market. Continued Commander interest in black mana acceleration spells provides the demand floor; the main risk is the niche utility making broad demand growth difficult to sustain at elevated price levels over time.
