1. Make more types of boxes:

• Gun Mettle/Tough Break crates that give weapons and could give strange or unusual weapons.
  
• Haunted Crates that only give out Haunted quality items (with a teal-green glow), and only halloween unusual effects
  
• Invasion crates that only give out invasion themed items and only invasion update unusual effects.
  
• Robocrates that only give items and unusual effects from the Robotic Boogaloo update.

2. Wearable hats and Usable weapons.

3. Strange quality items that display a message when you get a certain amount of kills with them.

4. More unusual effects.

5. Vintage Lugermorph!

6. Fix the lingering effects after deletion. (e.g. Aces High and Dead Presidents having a card or dollar stay around, bats, the tribal circles)
