Sadly, I tend to see both a decent chunk of hydras and by default at least one spore. And even with 4 phoenixes, 20 seconds is gonna be about two or three ovies. A pain, but I tend to see ovies overproduced for scouting anyway.
Though now I'm remembering running into a ton of hydra while going air and still winning due to the magic of phoenixes. Weird, it's like phoenixes are good or something.
