I thought we had this more fleshed out than we appear to.
Basic concepts:
- Zone Carl when possible. High-angle lobelia tend to actually reach Carl, while low-angles will bounce off Nirvana and land in front of her. Use that as you see fit.
- Pumpkin can be considered significantly less useful in this matchup. It can't stun Nirvana, and it will rarely reach Carl intact.
- George is still good for applying pressure and getting you out of pressure. Remember that Carl has a lot of ways to kill George, though.
- 6B. This move is your friend. Poke Nirvana with it every time she activates. If she uses a move that she cannot be hit out of, jump cancel and dodge/block/shoot a lobelia/hit Carl out of his air approach/etc.
- 5B. Works the same way as 6B, but with shorter range.
