The decorider has 420 possible settings: which is the cheapest?
Ive created an Exel-sheet… same the last 3 years. So I know it is working. It lists all 368 items sorted by level, then festivation, then decor. Every decoration has 8 ways to be created. The sheet calculates all 8 prices as soon, as you enter a 1 (or 2 or 3 at level 5) into the blue column C:
The cheapest setting is shown in green. The column of the green price (arrow) tells you how to set the Decorider: here Snowflake (New Year), I (Level I), Dekor: Kitchen
Unfortunately to make it work, you have to fill all your missing decorations into column C : so use it when you only miss the last decorations. Which ones are missing: your albums shows you:

When sb is interested: here is how the calculation works:
for example: all random:
We need first the number of items we are searching for: lets say we are only missing 3 items: 1 from level I and 2 from level IV against all items: 368. But Level I items are 16 times, Level IV 2 times more likely to be crafted than level V (wich also have 3 times more items then every other level this year): So we WANT vs. ALL is:
All items could be crafted several times: the odds arent changing: so its a bernoulli-chain and 100% is never possible. So the sheet calculates how often you have to repeat using the calculator to have a 75% winchance (you can replace this win chance with "search and replace": it has the form of: 0,75):
this is multiplicated with the cost of the setting minus the average shard-refund we get, when we smash the crafted item again and end up with a price of 7916 shards.
(Big Lootboxes)
And Ive seen some wrong calculations: with this formular you also can calculate how many big lootboxes you need to get the Bisonte with a 75% chance:
