I dig the mechanics of this card, but I'm not a fan of the Plant Cleric Knight. It feels weird to see those three creature types next to each other.

That's fair. The creature type is mostly a throwaway, but it's meant to be a sapient, humanoid plant (something like Leafkin, but with flowers). Cards I design that are meant to be paladins are generally cleric knights: see Fatigue's Paladin and Officiant of Chaos as examples.

I'll disagree on the creature types. Cleric Knight clearly is a great class combinations for a Paladin.

The hybrid cost is a little weird, but not necessarily wrong here.

I think probably the weirdest part to Lev was the Plant component. 😅

The mana cost is admittedly odd as well, but it's the same as Bant Sureblade.

I really feel like they should be Knight Clerics, not Cleric Knights

Ooh! How about “You may cast the top card of your library if it’s a creature card with power less than CARDNAME.”?

That's a viable option as well.
