I know it will not become a thing and this card will probably be underused for ever, but can we try to buff it a bit?
It is so gimmicky to use that no one finds it worthy.

Suggestion
Can we change its ability to ' while its attack is less than 3, it cannot attack.' Followed by the rest of the text.
Omitting the 'cannot defend' part will not make it strong, but at least it will be having some backbone to hit back.
