Fae Knight Lancelot, Melusine, is a highly unique Servant. We’ve had some Servants in the past with different NP animations, or even NP names, depending on ascension level. Melusine takes that one step further, completely changing her NP’s typing and effects when she hits third ascension. Her third skill also lets her switch from ascension 1 or 2 to ascension 3 (but not the reverse) giving her a degree of flexibility unusual in a Servant.
That said, in most cases, she’ll be operating either as an ST Arts unit or as an AoE Buster unit. Due to the nature of how FGO’s supports work, it’s difficult to put Melusine in a situation where switching from Arts to Buster doesn’t result in lessened performance in one or both of those roles. This means Melusine is functionally two separate Servants with similar kits, and in either use case she’s just okay relative to her role. Melusine is a decent Servant in either form, and her NP-change gimmick will likely be extremely useful in some very specific cases, but all in all she’s a lot more flash than substance.

Melusine is a highly unusual Servant with an interesting gimmick. There will probably be a handful of fights or farming nodes where her ability to switch from ST Arts to AoE Buster will make her the best pick, but these will almost certainly be few and far between. In most cases, she’s going to be either a pretty good Arts unit or a pretty good Buster unit. There’s value in that flexibility, for sure, but it’s not as remarkable as her being the first Servant with two completely different NPs would suggest.
