For example, most challengers deal dark and earth.
What icon type are most challengers most susceptible to?
I don't think anyone has done an analysis like that before, and it would be a difficult thing to standardize.
Does a T13 pet care about which icons are most commonly blocked in the easy-very hard challengers? How do you weight the icons?
I think the best answer you could get would be that the only icon type that I know that I have sought out for on a challenger is water.

Using Silvy's spreadsheet I got:
| Type | Attack | Defense |
| Dark | 566 | 248 |
| Earth | 393 | 268 |
| Fire | 339 | 181 |
| Ice | 236 | 181 |
| Light | 243 | 172 |
| Magma | 209 | 172 |
| Physical | 521 | 277 |
| Water | 339 | 207 |
| Wind | 327 | 212 |
So it looks like they deal dark and physical the most and defend dark, earth, and physical the most.
