Iono

Iono 29/38 from Ruler of the Black Flame Deck Build Box is worth about $0.45 ungraded, according to Cardmarket's monthly trend for September 2026.

This card sells for very little, so its price is Cardmarket's monthly trend, not a median of completed sales. It can be a few cents off: treat it as an indication, not a precise number.

If you add this card to your portfolio, it won't be counted toward your total portfolio value. It's here so collectors can still track their collection's progress, without inflating the total with low-confidence prices.
