FINALLY I DID IT!!!
I've just won against Lance and therefore I finished the challenge. Btw can I change my pokes now to what I want? Like evolving gastly or teaching water moves to quagsire, etc.
Team:
Nhanhoso, Lv. 43 (Female Quagsire)
Serious, Wide Lens (for Blizzard)
-Headbutt
-Amnesia
-EQ
-Blizzard
The MVP! This thing was awesome. It was my best deffensive pokemon and, with the help of some hyper potions, it defeated all of Lance's Dragonites.
Braseiro, Lv. 48 (Male Flareon)
Lonely, Charcoal
-Fire Fang
-Quick Attack
-Fire Blast
-Bite
Wow! It went from being my most useless poke (when it only had quick attack and bite at Lv. 40) to being the second best. It destroyed Will and Koga almost by itself (excluding slowbro and muk).
Gasosa, Lv. 43 (Female Gastly)
Modest, Choice Scarf (Gasosa had both zoom lens and scarf when battling the E4 but against Lance I wanted him to outspeed and OHKO Gyarados and revenge kill zard so I gave him scarf)
-Hypnosis
-Shadow Ball
-Thunderbolt
-Dream Eater
It was the second best till the E4 but here it disappointed a bit. It failed to OHKO Gyarados with T-bolt (but paralyzed it, got parahax and managed to 2HKO without being hit) and failed to revenge kill Lv. 49 nite when it had less than 20% Hp left which almost cost me the match.
Bolinha, Lv. 44 (Male Qwilfish)
Bashful, Shell Bell (it had scarf till Lance)
-Revenge
-Waterfall
-Brine
-Rollout
Humm, what should I say about bolinha? Well, it almost soloed Bruno with waterfall thanks to scarf and swagger boost and revenge killed Karen's Gengar when all my remaining pokes would be easily finished by it. It wasn't a great poke but it sure helped against fighting types (it also almost soloed Chuck).
Reltnats, Lv. 38 (Female Stantler)
Careful, King's Rock
-Confuse Ray
-Zen Headbutt (Astonish)
-Hypnosis
-Stomp
Flinch and confusion is awesome! But it was too hard to train and only learned zen headbutt on the final battle against my rival. It helped by soloing Machamp and Intimidating Lance's Nites.
Folhinhas, Lv. 46 (Male Meganium)
Bold, Miracle Seed
-Light Screen
-Synthesis
-Frenzy Plant (it had magical leaf till E4)
-Safeguard
Who the hell said starters are strong??? It was hard to train, it wasn't an offensive threat to anything but geodudes, gravelers, golems and onixes and it couldn't even do its defensive job well!!! All in all, the LVP of this Challenge.
So I'll start my platinum challenge in a few days.
Edit: Wow, this was my bigger post ever...
