>>55389877As for Surskit, Surskit was far more mobile than Regice. Brendan's strategy was to use Rest, not to dodge like Surskit did.
Actually, I'm watching the Regice battle now to refresh my memory, and other than the first slip, it seems like the slippery ice never bothered Pikachu again. It's as if it wasn't even there.
And this is besides the point, but... Man there's a lot of stuff in this episode that is just poorly written. Other than the ice field never coming into play again, Pikachu uses two iron tails in a row because... it just does? Why would Ash ever not use two iron tails in a row then? Not to mention Pikachu did this while Airborne, as if there was no knockback on either side. And then, while still airborne, Pikachu dodged an Ice Beam. How? It's in the air, it can't move. I can't even with this. Ugh.
