Been dabbling in the Battle Hall lately and using some weaker species for fun - makes you appreciate how, even in Gen IV, some Pokemon had really limited movesets back in the day. Cherrim for example learns almost no attacking moves that aren't Grass or Normal.
One way of expanding a small moveset is Natural Gift, which I've been experimenting with on some sets. Always liked the idea of this move, but it's frustratingly hard to use in concept because it's often very difficult to justify giving up a moveslot and your item slot for the sake of a move that has no additional effects, usually has no STAB, and isn't especially strong.
The way they distributed the types out among the various berries is genuinely quite well-done; there's no Steel-type move with the maximum possible BP (but who cares, it's Steel in Gen IV). Something neat is that all the type-resist berries all yield a 60 BP move of their own type, so that's at least easy to remember. Though the circumstances in which you'd want a resistance to a certain type and also a move of that type are quite uncommon, frequently making it that much harder to justify sacrificing your item slot. 60 BP is quite weak, though, so if you want a slightly more powerful move you have to turn to the rarer berries: Watmel-Belue and Liechi-onwards all yield an 80 BP move of various types.
But considering how rare and special the Lansat-Rowap berries are in particular, it seems really underwhelming for them to just be a standard 80 BP move with no other effects. Hell, the Starf and Enigma berry being a single type at all seems kind of counterintuitive given that the Starf is meant to be a blend of all flavours and the Enigma is supposed to be a mysterious berry with untold powers.
It's all academic as I don't have most of those berries in Gen IV but hell, you'd think their effects would be an attack with typeless damage (yes, I know this is hard to make work effectively from a mechanical standpoint) or a move which always hits super-effectively or something. Idk, just something a bit more interesting than... that.
Gen VI, at least, upped Natural Gift's power across the board before Gen VIII snipped the move from existence. Which probably wasn't that much of a loss. It's a move that never really lived up to its potential outside of some very limited uses.
