[@Gemini Token] Do you mean playing a Biovisionary, or summoning one? I don't know how that would work in a duel, similar thing with Battle of Wits. However if you simply mean a very capable biomancer go for it.

I believe Biovisonary could be something similar to creating a bomb. once all the pieces are togather it's just a simple detonation to win the day. Battle of wits on the other hand doesn't exactly work unless you have like... 200 spells which is way way way way above avarage. Bordering Urza levels here.
