Oh yes, I forgot this was being used in a rainbow deck.. Perhaps if this was simply given an element? Life, maybe. It does associate with Scorpions, and it seems that Permanents and Spells in the "Other" category that aren't shards don't get put into the game very often. This would probably have a better chance of getting voted for if it wasn't in the Other category. Just IMO.
Also, (lol) I meant to change the actual "Art by EmeraldTiger" inside the card itself. Also, make sure the card text matches the table text word for word and punctuation for punctuation. Made that mistake before. Doesn't seem like a big deal, but the Curators don't like it for some reason. (Fix the periods at the end of your tables)
