Well, unlike most decks, Buzzwole only needs 1 Lele to work. This is because of Octillery(BKT-33) provides the backbone of draw support to the deck. And if you're really that tight on cash and don't plan on playing in serious tournaments for a while, you can suffice with 0 and just play more draw supporters.
Buzzwole/ Lycanroc is shaping up to be the best deck in format with all it has going for it and what little it has going against it.
