Enhanced Card Throw

You grab a single playing card and shroud it with purple arcane energy and fling it at one creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 piercing damage. Hit or miss, the card then explodes. The target must succeed on a Dexterity saving throw or take 2d6 piercing damage. On failed save the targets become blinded for 1 round and cannot take reactions. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the piercing damage increases by 1d6 for each slot level above 1st.
