SD LUCARIO IS A BEAST. He can take on (assuming +2 which is actually pretty easy. Switch into ferrothorn, Choiced Landorus or Chomp or Ttar using Stone Edge. Switch into Forretress. Switch it into a bug, rock, dark, ice, steel, grass move or toxic and proceed to scare out the Mon. On the switch you use SD :D) many threats such as tornadus and therian, thundurus therian, breloom , infernape, mamoswine, ttar, gengar, terrakion. All of these guys are pretty much OHKO by either ExtrememSPeed or Bullet Punch, or they can die from switching into CC. Also Lucario sweeps late game. Meaning the opposing team should be worn. Landorus and Garchomp for example get OHKOd at like a 60-80% HP Range. Lucario also easily smashes walls not named Landorus-T and Gliscor and Jellicent and SLowbro. Genesect also gives him hell (but switching into a +2 CC will end him forever >:P) My point is, Lucario is actually still vvveeerrrryyy potent in the right hands with smart plays. My current team that I will RMT soon, speaks for itself.
