Is This Faerie Too Powerful?

[Sporegorger_Dragon]

Let us assume a Modern Horizons or Commander type set, would this be at all okay? (Disregard rarity for now.)

Sneeze-Powder Faerie
u
Creature - Faerie Rogue (U)
Flash
Flying
When Sneeze-Powder Faerie enters the battlefield, counter target spell with mana value X or less, where X is the number of creature tokens you control.
1/1
"I'm not a token, so it's okay!"

So, thoughts?

Comparing it to Spellstutter Sprite it seems reasonable but also, it's possible it may have to be a 0/1.
