Hopefully I can swap for the 7 I need without spending any MP/AU.
I sure hope obtaining all 10 will be more achievable compared to all other event instruments. With the last event instrument I clicked enough presents to win the trading card, yet I had to buy 5 Kazoo. Here's to hoping this event is better for the instrument. 
Very happy that they're more common. Not even a week into the Halloween events and I already have 11 Skull Violins from Elger. Spooky Drumset from Trick or Treating is appearing rather rare. I've only managed one so far. 
Submitting my ticket at past midnight probably wasn't the best idea. I missed the Burple avatar on my list, as Slater Stalker quest just kindly reminded me. ETA 4/3/17 - I just got my missing Burple avatar back from the temple.
Over half of my missing items are obtainable only once per account. All the freebies I was compensated with won't cover the cost of buying something like Breeze Potato Chips or Bubblegum Snowcone from Royal Fairy. Especially as both of those items seem to not exist anywhere in trades or galleries. All those Christmas musical instruments that I had bought and put in gallery - not all got returned, so I had to re-buy between 2 and 5 of each instrument. But my biggest loses are from missions. I do 3 mission levels almost every day. So that's roughly 3 LE potions a month, factoring in that I occasionally fail the levels. I have been doing Priscilla mission as often as possible since it was released in August 2016, so that's probably 6-7 Eyru makers that are gone. At 10m or higher each, that's a lot that I'm missing. Plus there's all the lower end LE potions that I've gotten since last June.
