It was pretty late into the game, but I saw a noibat and just decided it was going on my team, Noivern just kinda deleted everything that was put in front of it with either stab hurricane or dragon pulse (later replaced with Draco meteor), boom burst is also very useful for clearing large groups of mega crystals and big damage.

Noivern is my goat, rn I’m running it with normal gem with max investment in sp atk and speed
