Lucario or Blastoise?

Question

My team is:
Lucario/Blastoise (mega both special)
Diggersby (physical)
Greninja (special)
Infernape (physical)
Noivern (special)
Aegislash (physical)
Current Lucario set:
Timid nature
252 Sp.atk/252 Spd/4 Hp
Lucarionite
-Aura Sphere
-Flash Cannon
-Dark Pulse
-Nasty Plot

My Blastoise set:
Modest Nature
252 Hp/252 Sp.atk/4 Def
Blastoisnite
-Aura Sphere
-Dark Pulse
-Water Pulse
-Dragon Pulse

Both work well but just need one. Which one?

Answer 1

Blastoise

You already have several frail sweepers, so you could do with a bulky Pokémon such as Blastoise. Its typing is better too, Lucario's Steel typing adds to your team's Ground and Fighting weaknesses.
