Magma [Rainbow Foil] #38 2018 Ultra X Men Marvel — Card Value

Which version do you have?

For the cheapest way to own it, grab the Standard version at $3. The Rainbow Foil version offers a slight premium, likely due to its visual appeal or minor rarity, but the difference is minimal at only $3. If budget is the primary concern, buy Standard. If you want the slightly more desirable variant, the Rainbow Foil is worth the small extra cost.
