Ways To Manipulate Dice Pools

I've been pondering mechanics for the magical girl game I'm designing. Lots of success-counting dice pool games use a mostly very simple mechanic – +/- dice to your pool. This is a good mechanic because it's very easy to grasp. However, I've been inspired by Dicey Dungeons and the unique class mechanics in the game Nimble, I think there's interesting room even in a relatively narrative game for pool manipulation mechanics. So, here are some of the mechanics I've brainstormed. This is not an exhaustive list, and certainly many of the ideas are bad, of course. Hopefully this can be useful to anyone else searching for dice pool inspiration.

Default Assumption: Roll a number of dice; count a Hit at or above Threshold (usually 4+); compare Hits to Target Number

1. Explode 6’s
2. Increase Threshold by N
3. Decrease Threshold by N
4. Add N dice
5. Subtract N dice
6. Reroll N dice
7. Reroll 1’s
8. Reroll failures
9. Reroll successes
10. Reroll all and take the new result
11. Reroll all and take the higher # of hits
12. Reroll all and take the lower # of hits
13. Count only highest N dice for hits
14. Count only lowest N dice for hits
15. Add N dice and drop lowest N dice after rolling
16. Add N dice and drop lowest N dice after rolling
17. Choose N dice to change to desired face
18. Use two colors & compare, cancel, add, or subtract
19. Upgrade die size by N before rolling
20. Downgrade die size by N before rolling
21. Change how many Hits are counted on a certain face
22. Divide Hits between multiple Target Numbers
23. Use excess Hits for extra success
24. Use highest die result to determine extra success
25. Use lowest die result to determine extra failure
26. Use pairs of a certain face to determine extra success/failure
27. Count certain face for extra success/failure
28. Increase the Target Number
29. Decrease the Target Number
30. Roll Target Number (usually 2xTN dice)
31. Roll a portion of of the Target Number
32. Convert the Target Number to dice subtracted from pool
33. Convert N dice to flat Hits
34. Add N Hits
35. Subtract N Hits
36. Split pool into multiple smaller pools (resolve separately)
37. Roll in stages (first roll determines how many dice are rolled next)
38. Set aside dice for later use before rolling
39. Set aside hits for later use
40. Vary die sizes within the same pool
41. Manipulate/determine extra success/failure by the die in a certain position
42. Cap maximum # of hits
43. Floor minimum # of hits
44. 1’s cancel Hits
45. Count distinct values only (duplicates don’t add hits)
46. Count sequences of hits/straights for extra success
47. Botch if no hits and ≥ N failures
48. Botch if double 1’s
49. Critical if all hits
50. Accumulate 1’s or failures for later penalties
51. Reroll lowest die for each pair
52. Merge dice of certain faces
53. Merge pairs of dice
54. Replace results instead of rerolling
55. Roll, then assign dice to certain abilities/powers (a la Dicey Dungeons)
