Thanks Dude, interesting thoughts - I haven't had a chance to try them but it does sort of give me the sense of making the swarm work, rather than thinking specifically around straywood.
I think I looked at the straywood aviary as being something that would be like a whirlwind of birds tearing down the enemy and while I think it could be in theory, getting the balance between establishing the board presence smaller swarm creatures need and trying to pump out the birds never quite fell right.
One approach I might try is a swarm as a build deck rather than aggro, building the board more while looking like I'm going to play aggro badly
