Norfair!! (nofair amirite!?)
The ledges on this stage are ridiculous. And ICs have pretty sweet options at the ledge IMO.
You can tether to whichever edge you want, and poke at the enemy with Uairs from below all the platforms, with lots of ways to recover. Side-B recovering is easy and you can choose whatever platform you want to return to. It's hard to gimp a solo IC on this level, because unless you're below the lowest platform, you have
choice in your recovery.
And the multi-stage platforms give weird desync options for the ICs.
And Ice Shots are hilarious here because they slinky down from the top platform to the lowest. Of course, ice shots are
more ridiculous on stages like Green Hill Zone, where they roll back and forth and back and forth, totally messing with your opponent! I like to desync the ICs so Nana spams ice shots while I chase the enemy with smashes... hard to pull off though.
That all being said... Norfair can fail hard if your opponent is also good at abusing it. And there's not as much grabbing opportunity. But it's so neat
Green Hill Zone is also kinda meh cuz the roundedness can mess up CGs and it makes Blizzard kinda useless too.
Jungle Japes is a neat stage for ICs too, IMO. The ledges are easy to play with, with up-B and side-B options. And Nana-spiking people into the water is pretty sweet
A good level if you want a quick, under-handed match!
