Wait 3 minutes for the Sova to get into position, or 100 seconds with Morph by going ahead of them to break the shot blocks as they get there. This can be further reduced to 45 seconds with a Super by knocking a Sova off after it exits the morph tunnel. The other Sovas can be farmed or used as a backup.
