Halloween Madness

This marks a year cycle of events, but with new cards this time, and like the recent Rainy Week event, we have the campaign mode with chapters. There is a marathon which lasts throughout the 21 days whereby the final top 500 get the event mythic card.

Getting Little Pumpkins gives you the same amount of Infernal Cups. The more Cups you got the higher you are in the Marathon. At the end of the Marathon the leaders are determined, and the Final Prize is given.

Pumpkins
The event features three types of Pumpkins : Little, Scary and Infernal Pumpkins.

Little Pumpkins - obtained from opening duel chests, beating campaign chapters, purchase using gems, or quests which open in phase 2.

Scary Pumpkins - obtained from beating campaign chapters (with 3 stars for the 1st time only), or picking in a Little Jack Coffer.

Infernal Pumpkins - obtained from winning the event daily tournament (top 50 with most Infernal cups each day), or picking in a Scary Jack Coffer.

Coffers
Little Jack coffer - 3 pickings, 1 unique event card and Scary Pumpkins instead of cards are guaranteed. Unfortunately, you may be forced to choose between Scary Pumpkins and a unique event card.

Scary Jack coffer - 5 pickings, 1 unique event card and Infernal Pumpkins instead of cards are guaranteed. Likewise, you may be forced to choose between Infernal Pumpkins and a unique event card.

Infernal Jack coffer - 10 pickings, many unique event cards and artifact are guaranteed. Likewise, you may be forced to choose between Artefact dups and a unique event card.

Event Cards
These cards can only be obtained by opening the appropriate coffers during the event.

Artifacts
Obtained from the Infernal Jack Coffer, duplicates of the same artifact are combined to level it up, then inserted into any red card (without an ability). Assuming you have enough dupes, it is possible to upgrade an artifact during the next week (when it's no longer available), or even after the event ends, exactly like card seducing.

Phase 1 artifact : Hell Fire (10-20-35-50-65%).

Phase 2 artifact : ???

Phase 3 artifact : ???

Campaign
Like old events, campaign mode takes place in a familiar map, where battles require some energy, and you fight against 7 enemy cards like in duels. While you can beat chapters with just 1 star (1 card left), you want to win with 3 stars to earn Scary Pumpkins. There are 30 chapters in phase 1 :

Path
Starting from phase 2, you can earn Little Pumpkins and Infernal cups by completing Path quests. Completed objectives will not reset at the end of the daily tournament. There is a X5 inflation for the Little and Infernal Jack coffers, and only X3 for the Scary Jack coffer.

Daily Contest
In phase 3, the coffers' cost did increase by X5 for the Little and Scary Jack coffers (a total of X25 and X15 from phase 1!), and X3 for the Infernal Jack coffer (a total of X15 from phase 1!), and there is no event daily tournament, but you can earn Infernal Pumpkins and marathon pts, in addition to the 2 remaining event cards (Silk Lady and Obsessed) from the regular daily tournament measured in mojo as follows :
