I have Mulan at level 2 and don’t have Mushu but have a wand so 1/4 chance of Mushu (currently) but only for the first, not dupes, obviously. I have 4 charges.

Should I buy series ii boxes or gold in an attempt to use fewest possible charges for the Mulan event? Mulan is ahead, but it’s a 1/136 chance for dupes, while, I don’t have Mushu, it’s only a 1/18 chance.

I need one at level 4 to finish the event and it will be my first finished event that’s not a card collecting bingo. I’m going to pick a box and keep buying it until the event.

EDIT: my eyes do not function well and Milan is series ii, not gold. Basically I need to get 100 series ii boxes. Decisions made.
