I just found this thread and gotta say - it looks very interesting.
Since this week's victim is Mega Latias, here's a decent lure:
Garchomp @ Lum Berry / Focus Sash
Ability: Rough Skin
EVs: 252 Atk / 4 Def / 252 Spe
Jolly / Naive Nature
- Stealth Rock
- Earthquake
-
Dragon Claw / Outrage
- Swords Dance / Fire Blast
With all the TankChomp running around OU these days, some people forgot that the offense suicide Garchomp lead is still a good 'mon to run. And in this case, offense. Since Mega Latias would always want to switch in on a predicted Earthquake, Chomp can predict the switch, outspeed and take down Mega Latias with its powerful Dragon-type STAB options. Of course, it won't want to switch on a predicted Dragon Tail. The reason why I slashed the Sash set and the Lum set is because suicide lead Chomp still lures Mega Latias nicely since it outspeeds (assuming that Mega Latias speed creeps up to the slower Garchomp). As an added bonus, Chomp helps with offense 'mons AND lures some other stuff like Mega Sableye and Rotom-W too.
Calcs:
252 Atk Garchomp Outrage vs. 248 HP / 68+ Def Latias: 362-428 (99.7 - 117.9%) -- guaranteed OHKO after Stealth Rock
252 Atk Garchomp Dragon Claw vs. 248 HP / 68+ Def Latias: 242-288 (66.6 - 79.3%) -- guaranteed 2HKO after Stealth Rock
