I tried the Greenscales with Nilfheim, Braxas, Charos, Zelrig, Mimring and Othkurik. I tried them against a few armies that included 4th Mass army (with Thorgrim), Minions/Atlaga and Q9/Raelin/KMA/Rats.
These were my observations:
- In (almost) each case, they need Raelin to help protect the dragon.
- Keeping the dragon alive is paramount. The Greenscales are a weak squad without the dragon/lizard king.
- In most cases, 2 squads of Greenscales is enough. Otherwise, you run the risk that the dragon will get killed first.
- Nilfheim/Raelin/GS/other is a very good army. I liked Nilfheim/Raelin/GSx2/KMA best. It was fun to play and competitive against anything I threw at it.
- Braxas/Raelin/GSx3 was a very good army against high point common armies. The Minions crumbled. It had big problems against Q9. Against 4th Mass, Braxas needs to get in close and she gets shot from distance. I tried this with both GSx3 and with GSx2 and a hero to close the remaining points. With too many GS's, Braxas dies and leaves the GS's helpless. With 2 squads of GS's, there aren't enough points left (in a 500 point format) to have another strong offensive threat.
- I tried Charos/Raelin/GSx3. (I also tried it with Charos/GSx4/filler.) This a fun army. Charos needs Raelin the least. The Charos/GS vs Minion/Atlaga match up was my favorite battle. (The Charos/GS army barely won. Minions hate counterstrike.) This army really suffers from rats.
- I couldn't get Zelrig to work. If you use the Z bomb, the GS get left behind and Zelrig gets swarmed and dies. The Greenscales aren't good without Zelrig. If you move up Zelrig slowly, you lose the Z bomb. Zelrig/GS wasn't really competitive against any of these (very good) armies.
- I used Mimring/GSx2/Raelin/Q10. This army did well, but it was more of a function of Raelin/Q10. When I play Mimring, I try to hop around the board and set up fireline. This isn't easy to do when the Greenscales are trying to act as a screen. I had trouble using Raelin with Mimring because I couldn't get Raelin to be close enough to Mimring.
- I used Othkurik/GSx2/Raelin/10th Reg x 2. Othkurik played similarly to Mimring. I had trouble using Acid Spry to great effect because I spread out the opposing figures. Still, Othkurik was probably better than Mimring because I didn't feel the need to move Othkurik around as much. This was surprisingly competitive against the 4th Mass, but it got crushed by Vydar/Rats.
Edit: In my opinion, Greenscales with Nilfheim and Raelin are a A/A- team. As a result, I would give the Greenscales an "A-" ranking. I could possibly be convinced that they could rate an "A".
