I think that both of these decks are better separate. Vespiquen and Night March may seem similar, but they are different. Vespiquen requires more discarding and less aggression, while Night March is just all out aggression. One of the reasons that Flareon and Leafeon did well in Night March was that it helped VirGen and Toad. With the rotation, VirGen will rotate and Toad will be replaced with Vileplume IMO.
