Some good suggestions regarding 5 star black birds. I certainly was hoping to get the black bird from the Soccer Stars event just past as my eventual Carson replacement. Sadly, despite exhausting my stash of gold tickets, I didn't even get the yellow bird. That highlights the inherrent problem when it comes to finding a good 5 star black birds, they're just not available outside of specific events. Even Dutch and Byron, who I assume can be got from the odd lucky hatch, are easier to acquire from EM (either cheaply or very expensively depending on your luck). So for me, it's push on with Carson, using Xeno +30% boost to Special Forces to augment him and Birdstanio (then Murphy when he's levelled enough to replace him). Once I hit the pig scaling barrier, I'll likely swap Carson out for Claude, move Xeno to Carson's spot on the team and make Claude the leader. Even though Xeno's SS isn't fantastic in terms of range or damage, she picks up powerups and pulls pigs across the line, and sets timer pigs up for back attacks. Of course , that's assuming I don't get another 5 star black bird before then.
