It takes 15 to maken 1 finish all productions. It takes 12 epic Halloween23 kits for each tarot to max out. If someone had participated actively during Halloween23 + DC and understood the card game and had at least 1h daily to their disposal it's probable they could've obtained an golden upgrade for the tarot for free. To speed up finish all productions items to 7-8 collections (w/o BG).
The Halloween event had 35 rush quests and 21 daily quests. Assuming one of used all rush items on the 35 rush quests, leaves 21 daily quests. The dailies required once productions of 24h and twice 8h productions. The event lasted +/-28d. Assuming the player used the finish all only on the 24h production buildings and let 8h productions finish efficiently on their own, leaves us with 28d/15frag = 1,8+ finish all - 1 used = 0,8+ finish all * 15 = ~13/15 fragments. Assuming during that time 3 collections where lost. Ends up with 10/15 collections. Leaving the player with 5 collections which should be possible to get in a week.
Assuming the tarot lvl12 was constructed in anticipation of the rival and in case of an similar usage of finish alls during an future event prior to the rival quests. With an golden upgrade it's more likely one could be better prepared. Alternatively knowing now the rival could take us by surprise, we could save finish all for just 24h prods and the rival vs rushing any production quest of the rush quests from events.
