(already shown) Path 3: (8A)-(10A)-(9B)-(11A)-12C
Takes a further different path to get this variant (allowing Skylla to escape north), but it's worth it. I may have to retract what I said in Atmos Ring and claim this as the best Griswall variant. I had actually never had as much fun playing Wild Card as here, as I had to force myself to not go for the max possible score and varying things around... and it was so much fun.
Tied with Pinned Down, this is ACX's best populated mission, with a wealth of air and ground units to keep you constantly engaged if you switch it around. Off the bat, you're presented with ingressing armor columns, an aggressive Gripen squadron, and the laser ring. It's not perfect, because really, there actually aren't that many targets overall, not compared to other ACs, but the way the mission is set up and the pace of the enemy air spawns keeps the action going for a good while. And when you're bored, you can just kill the last ground units to switch on to the missile rush. An example of good mission design.
