What about when they run into stealth? I thought about running a Cuckoo/Jakeem Thunder type team, but couldn't see a nice way to deal with stealth.

That team of 3 cuckoos, Jakeem Thunder, and Wiccan is nasty. Add Alpha flight to Wiccan to boost his attack value. do not underestimate the amount of damage this team can do. I have played it and it is nasty. stealth is a problem however that can be countered by a BFC or aggressive play and map choice. It would be a problem to work around but so will be the high defense and cuckoos

That, mon ami, is when you CHARGE!!!!!!!!!!

That's exactly what I had to do for a Stealthy team when I played the Cuckoo Quartet with Prof X... and it worked wonderfully. Remember, as long as your cuckoos start adjacent to other cuckoos, you can also increase their speed values if you want.
