So I've finally figured out a decent combo to get biovisionary out for a win. Obviously this is just a casual deck, but I think it's going to do well.

Basic idea is to Unburial Rites Angel of Glory's Rise to reanimate, Burning-tree Emissary, Undercity Informer, and Fiend Hunter.

Using Fiend Hunter's ETB, exile Angel of Glory's Rise. Using the extra RG from Burning-Tree Emissary, use Undercity Informer's ability to sac her, mill yourself until you reveal a land (hopefully getting a biovisionary), use the other floater to sac fiend hunter, to mill again, and to return Angel of Glory's Rise. Doing this should net you more humans in the graveyard. Repeat this process until you've milled all biovisionary's in the deck and reanimate them!

Please disregard the mana-base for now. I'll work on it tonight. I'm otherwise open to thoughts and suggestions.

So the board state is you have a Fiend Hunter, Burning-Tree Emissary, Undercity Informer in the yard, then either hardcast or reanimate an Angel of Glory's Rise, use the aforementioned pieces to combo and mill yourself until you have all 4 Biovisionaries in your yard and reanimate them with the Angel to win.

If you can infinitely mill with the above combo pieces, why add the Biovisionary at all? You can just mill your opponent for the win. Wouldn't those 4 slots for the Biovisionaries be better spent on things that add consistency? Cathedral Sanctifiers could add some lifegain while you work towards the combo win (Huntmaster of the Fells does so too plus tokens, but that adds R mana you would otherwise not need), Tracker's Instincts for more ways to fill the yard (if you do add R then faithless looting is better).

Adding Biovisionary just seems like a win more.

The point is to just win with biovisionary. Sure, I could mill them out, but what's the fun in that? I've tried other methods but I'm trying something a little different for fun.
