Being a beginner myself I found that watching a ton of matches with good players really helped out. Basically the idea seems to throw stuff at your opponent and play a good neutral game until you can summon something and then move in (may differ depending on matchup). Throwing lobelias and using pumpkin to keep your opponent scared works out so far for me. If they block George you get a free mixup in many cases, a really simple way to get in (which may not work against better players or some characters) is to just summon pumpkin and then dash + wind, you move fast and have protection from the pumpkin. You can also kinda use pumpkin like a regular projectile to cover you when you are in recovery or just need something to hit them fast.
You can also use wind to give lobelias another trajectory which may be harder to deal with, this becomes even more powerful if you have a summon out.
Summoning George seems slower and riskier to me but I may be mistaken. At some times if you summon George your opponent may think they are allowed to dash in even if you have time to recover first, then you can either punish them trying to kill George or just block their offense and they will be forced to block / get hit by George.
I think it's important also to recognize when you are allowed to move in. At times you may be at frame disadvantage but your opponent might be scared or whatever so you are allowed to dash in or summon something.
Again, I am a beginner myself and my Rachel is pretty bad, so my advice may not be the best and I would love to hear a better player tell me I'm wrong. See it more like my thoughts based on what I've noticed in the few matches I've played rather than facts. Figured I'd post it anyway as it might help somewhat.
PS. Noticed you were in Sweden, if you are in the Stockholm area we can play offline some time, check out bitterharmony.se/forum for regional matchmaking. Otherwise I might meet you online some time
