Here's a few ideas for leads:
Darkrai - any ability - Mind Plate/Expert Belt
Moves - Dark Void, Dream Eater, Dark Pulse, Shadow Ball
Basic Strategy - Darkrai has high speed, so you should usually get the first attack. Dark void opponent, and proceed with dark pulse or shadow ball. If hp drops low, dream eater should replenish aqequate amounts, and a mind plate helps with this. An easy way to gain an early edge in a battle.
Honchkrow - Super Luck - Dread Plate/Black Glasses
Moves - Taunt, Night Slash, Steel Wing, Fly
Basic Strategy - Obviously an anti-stealth rock. Taunt coupled with high speed will almost always gurantee that your opponent can't use stealh rock. Night Slash for the majority of attacks, and of course Fly can help, should your opponent start to use Fly, Shadow Force or Sky Attack. A solid lead that can counter lots of entry hazard leads.
Lapras - Shell Armour - Leftovers/Lax Incence
Moves - Hydro Pump, Psychic, Brine, Avalanch/Blizzard
Basic Strategy - Solid Defence and S.Defence coupled with boastable hp, Lapras can take a hit, so your opponent can say "bye-bye" to a 1 or 2 hit K'O (excluding thunder). Blizzard should be your main attack, and Psychic to dispatch fighting types seeking to exploit your ice type disadvantage.However, if you equip lax incence, swap blizzard for avalanch, as the damage is the same (provided you get hit, which you likely will), the attack is ore accueate, and can't be "avoided", only "evaded". With that aside, Brine becomes incredibly powerful after damage is dealt to your opponent, a power rating of 130. That's more than blizzard and hydro pump. The leftovers should soak up any damage caused.
That's it for now, PM me if you feel you can improve my methods. I/m open to all suggestions.
