You should probably do the following in your table if you want it to have a higher chance of entering the Crucible:
-Capitalize the following words in your Table: Air (next to the Element section), Creature (next to the Type section)
-Remove the phrase (rare) next to the word Creature in your 'Type' Section
-
Fix the discrepancies between the card art and the table: "

:refresh
remove up to 3 poison and other unpleasant effects from the target"
...should be:
"

:Refresh
Remove up to 3 poison and other unpleasant effects on the target"
That said, this is one of the few ideas I'm okay with so far. It's simple enough that it warrants the semi-moderate cost, and it's something that

could afford to use (as the element of 'freedom', it should make sense for Air to have the ability to remove stuns from creatures). Of course, this card + Basilisk's Blood could become a problem...
