observations about V1.2 and suggestions for V1.4

[JonB]

Try it in pass n play, there are subtleties re uprooting, scrambling,etc
But, you can spawn a thorn for 1 wit, it has 2 health, and can immediately spawn another. So, you can deny access, create a shield, or zoom across the map and sit on a spawn or bonus space.
Killing or capturing a thorn also kills/captures everyone downstream of it.
