Oh yeah, since nobody looked into Plusle & Minun yet, here's a spread.

>Plusle
An ingredient powerhouse provided it's with another Plusle or Minun, but without that, it puts out 3/4 of the normal version. 300+ ingredients from a single source (or shared I guess, since you need 2) should safely top off your pot and rebuild any stockpiles you've been dipping into. If you somehow had 2, that would be far past overkill.

>Minun
Has basically no gathering power, so it's all in the pot size increase skill. This only really matters so that you can produce the highest quantity recipes, but that can equate to 50K+ per meal provided you have all the correct ingredients. At 10x per day, you can average at least 2 activations per meal, putting you at 69+24+24=117 pot size, easily enough to handle current and future largest meals. Its secondary ability should be rather decent given its activation rate, though randomness means it won't completely replace a regular E4E battery.

Both need large investments, but are INCREDIBLY strong. Activation rates put them on par with Vaporeon and Magnezone respectively, though you do need both Plusle and Minun on a team to see the benefits over either.
