Just tried pokemon lab and this is what i came up with..
Need help in Bold
Cresselia @ Lum Berry
Modest
Levitate
155Def/255SpA/100SpD
-Calm Mind
-Ice Beam
-Psychic
-Thunder Wave
--<p>I gave cresselia a lum berry so when my opponents pokemon </p><p>decideds to use a status inducing move I would be able to recover from it, especially poison.</p> Cresselia also has calm mind so i can start fainting other pokemon and at the same time i would last longer. The reason i put ice beam is because i need a counter for flying and dragon(flygon) types and after a few tries it seemed useful, but im not really comfortable with it, yet. Psychic, yes!, the STAB move i have, after a few calm minds i may be able to sweep half a team which seems to be better since i was able to finish 4 pokemons in a team using cresselia. Thunder wave for those pokemon who keeps on u-turning or baton passing and for the fast pokemons also.
Heatran @ Leftovers
Timid
Flash Fire
255Spe/255SpA
-Dragon Pulse
-Earth Power
-Magma Storm
-Will-O-Wisp
--There come a time when my cresselia is already gone and a dragon type appears, that is when dragon pulse comes to save the day(sort of). Earth power really works well since there are pokemons(lucario) who wants to destroy my heatran.Magma Storm, powerful even if not effective, i was able to defeat a starmie with it(2HKO) and heatran gets a stab from it. Will-O-Wisp to slowly defeat pokemons like dusknoir, and everything that levitates and survives magma storm.
Kingdra* @ Leftovers
Timid
Swift Swim
255Spe/255SpA
-Dragon Pulse
-Hydro Pump
-Ice Beam
-Rain Dance
--Rain daaance..♪ with its speed doubling and power doubling Kingdra becomes more powerful. Dragon Pulse is used for dragon types and for other types which resists Hydro Pump. Hydro Pump becomes more powerful with rain dance and there is a low chance that a pokemon would survive it. Ice Beam is my secondary offensive move - defeats grass type, ground type, dragon type, and flying type.
Celebi @ Leftovers
Timid
Natural Cure
255Spe/255SpA
-Energy Ball
-Psychic
-Recover
-Shadow Ball
--STAB attacks energy ball and psychic with it celebi becomes more powerful. Energy ball eliminates water, rock, and ground types, while psychic eliminates fighting, poison and well that's just about it, but it is still strong. Shadow ball helps celebi eliminate ghosts types. Recover heals celebi if there is an oppurtunity.(still thinking what move to replace recover)
Gengar/Alakazam @ Leftovers
Timid
Levitate/Synchronize
255Spe/255SpA
-Energy Ball/Focus Blast
-Psychic
-Shadow Ball
-Thunderbolt
--Speed and Power these two pokemon are my all around type sweeper. They can cover their weaknessess. The pokemon i choose between them depends on which I prefer. Energy Ball for those ground and water types. Focus blast eliminates the main pokemon which kills me, dark types. Psychic and Shadow Ball STAB for Alakazam and Gengar, respectively. Thunderbolt gives alakazam and gengar more type coverage.
Persian @ Sticky Barb/Flame Orb/Toxic Orb
Jolly
Limber
255Atk/255Spd
-Fake Out
-Switcheroo
-Toxic
-U-Turn
--Whaa- really??! Yeah its persian the best cat pokemon. Fake out damages the foe even if it is little but a damage is damage(I only use this when I am holding Sticky Barb). After being slightly damaged by fake out - Switcheroo time. Toxic will be only used if not yet fainted. And if still alive time to switch out using U-turn and deal some damage.
