I think your Ivy is really good, however I think you should try using 7_8_9B+K when you are spaced out. That combo at the end isn't very efficient with the amount of meter IMO, however you could afford to waste it all anyway. GG.
I can't believe you've found ways to incorporate 44B + K. The only situation it ever works for me in is when your opponent is in a corner. Lol, I remember you getting me and someone else with it earlier.
Nice looking, but not worth the meter IMO - obv in this case you could afford to burn it, but generally I would go with the option below or other options^^
For that GB, why do the extra 1bBE~6b8 if you could do 6b8BE which does more dmg? Plus, it looks sexier, and you can do Smarty style at the end (214a after 6b8BE)
SCV 2p Ivy (SaneOne) vs. Cas Ivy (Moonchild_27) I landed a nearly 200 dmg combo and i was removed for it right after. No one asked him to try and use ivy. Lolol
