Strategy
Combining Haunted and Grim subjects the player to plenty of omens, but not without some proper recourse. Grim's added effect of removing Omens for solving 20 Cells without making a mistake allows a skillful player to remove not only the omens that Grim dumps onto them, but also any potential extra omens gained from Haunted's effect.
The other stage mods make for additional flavor, making it harder to complete the board after a mistake by cramming more monsters in. In tandem with Haunted, this makes any single mistake very punishing for the player.
Drop Condition
When you click a 
Spooker on a Graveyard Stage there is a small chance (~1/1000 ?) you will obtain Pumpkin Patch.
The most reliable way to spawn Spookers is to spawn large amounts of normal 
Cankers. Use 
Troll Cross with range extenders like 
Astral Spike. Increase the cell values of the target area with 
Pentagram or 
Swelling Rune.
If you have the recipe for 
Book of Ghosts this can be a one item combo to farm this sigil. Craft the book, and heart drops will spawn spookers, which can drop 
Candy and 
Fake Candy which create more heart drops. Spookers also drop more Book of Ghosts which increase the number of spookers spawned per heart pickup. The goal should be to go into Graveyard (6th stage in quest 2) with basically a full inventory of Book of Ghosts and a large number of turns of the Candy buff to carry you through the stage. Candy drop is turn-based, so for best results don't chord too much. Best to pick up hearts near the end of the stage since you will get a large amount of loot with each click on a pack of spookers. I'd estimate the drop rate at least for this technique is ~1/1000, but with 20 Books in your inventory (easy if you don't fill your inventory with items you can't remove) you get about 60 spookers/heart, so perfectly doable. (Current rate I have is 20 emblems/19494 spookers).
Thought Bubble can continuously clear the normal Cankers out of the way.
You also want enough health to safely click through Cankers, perhaps from multiple 
Alcohol. Alternatively, use 
Guardian Mastery to be immune.
Notes
Spookers spawn during the Halloween event, making this a limited time access Emblem.
