Well, if I should say Stratagem is interesting, even if I prefer Fidgit by far. This bias comes only down to versatility: after all, I can see Stratagem able to run no more than 2 or maybe 3 sets with significant variants, while Fidgit is much more fun to use because you can adapt him to what best suits you teams, your desires, maybe even your mood^^ agan, this is my opinion.
From a more objective point of view, im pretty interested in seeing how well this thing will face the main counters/walls like Heatran, Zapdos, Celebi and Togekiss. On paper it seems to have some good selling points, but I fear that, like Syclant, the sheer might of Steel powerhouses (Metagross, Heatran, Scizor) will hamper it badly.
Anyway, its too early to say anything concrete, I think
