Use Shiftry because I don't think I've ever actually used one and it could be interesting.
Store Breloom for its nifty abilities and versatility.
Release Ludicolo because frankly? I just think it's kinda overdone.
Use Dodrio because it's a bird representing the LADS
Box Magneton because its got a good type and can evolve into something cooler
Release Dugtrio because all its got going for it is cuteness and good speed
Use Snorlax because he is a good boy shaped like friend.
Store Tapu Bulu because messing with the bull is in fact how you get the horns.
Release Slaking because all he does it eat all my grass and call me a *****.
Use Mewtwo because it's really grown on me the past year
Box Dialga so I can control time when I need to
Release Kyogre back into the sea like a goldfish. Never did like it that much. Still pretty cool anyway, though.
Zubat, Tentacool, Oddish
Use: Oddish (It has two very useful evolutions)
Store: Zubat (Don’t usually have the patience to raise one, but Crobat is awesome)
Release: Tentacool (Not a big fan since they’re prevalent in just about every region)
Use Crobat. I love Crobat lol. I always have, he was my like. Second shiny? And one of the team members I regretted getting in a lot of playthroughs, he's cool looking and fast and hard hitting.
Store Vileplume. Idk why but most of the time I prefer Vileplume plus I feel like he's more useful than Bellossom.
Sorry Bellossom... go have a fun life out in the wild hun <3
