What are the checks and counters for Mega Luke? Please list them separately (e.g list the common counters for Luke, then all his counters) Thanks in advance :)
There are zero counters to Mega Lucario. However, it has checks, and there are plenty of ways to play around it. You simply have to tell if it is physical or special in certain cases, which is, admittedly, easier said than done.
Can check any variant:
-CB Talonflame
-Physically defensive Zapdos
-Physically defensive Moltres
-Choice Scarf Genesect
-Choice Scarf Keldeo
-Focus Sash Alakazam (checks everything lol)
Can check only Swords Dance:
-Physically defensive Mega Venusaur with Earthquake or HP Fire.
-Gliscor and Landorus-T IF no Ice Punch.
-Aegislash IF no Crunch.
Can check only Nasty Plot:
-Noivern.
-Any faster mon that can OHKO, or any priority that can OHKO, IF no Vacuum Wave.
-Aegislash IF no Dark Pulse.
Of course, beating a Mega Lucario is easier said than done. Klefki can cripple it with Thunder Wave and Dual Screens, and whatever teammate that comes in to revenge kill for it will have an easy time. Burning it will decrease its longevity at worst and completely cripple the Swords Dance set at best. You also have to scout for which set and which coverage moves, which can lose you a mon or two potentially.
