>>36420075My autistic self decided to run each of those through the damage calculator to see how they all fared at level 60 with standard competitive setups against a level 60 neutral natured Ultra Necrozma with +1 in every stat but no EV investment anywhere.
The results aren't pretty.
>Pollen Puff RibombeeDoesn't OHKO even with Moonblast and gets outsped and BTFO by anything not named Dragon Pulse.
>First Impression GolisopodDoesn't OHKO unless you've gotten a Choice Band on it, and it dies to Power Gem.
>Leech Life AraquanidCan't even 2HKO without a boosting item, and will certainly be 2HKOed itself before getting a second Leech Life off.
Keep in mind, these are absolute best-case scenarios, where you have perfect IV spreads and full EV investment and are actually at level 60 with U-Necro instead of lagging a couple of levels behind it.
