>>22271498>Without STAB Gallade is pretty weak (For a Mega)>165 base Attack with a 120 BP Fighting-type STAB and Swords Dance is pretty weakMega Metagross is S-rank right now. Mega Gallade's STAB of choice hits harder than anything Mega Metagross has to offer, even when factoring in Tough Claws.
The only Megas that are both faster AND stronger than Mega Gallade are Mega Lucario, Mega Salamence, and Mega Rayquaza. Yes, Mega Medicham is stronger on the first turn, but between the infinitely better Speed tier and the incredible value of Swords Dance, Knock Off, and passable defenses Mega Gallade is far superior to its multi-armed rival.
