So, I have a level 63 Starmie with Modest nature (+Sp.Atk -Attack) that I have seriously EV trained in the 3rd Gen. I believe it has 252 EVs for Sp.Atk and 100 for Speed, but I can't remember now what the spread was over Def, Sp.Def and HP. (I do remember I was scared by the typical Special Sweeper 252 Sp.Atk, 252 Speed & 6 HP setup, and gave it better defenses!). The stats are: HP 170, Attack 105, Defense 158, Sp. Atk 181, Sp. Def 136, Speed 166. Not amazingly fantastic, but I also don't remember its IVs. After catching quite literally an entire box of Staryu, I went with the first one that was both Modest nature and Natural Cure ability, as I figured that was more important than anything else. In the 3rd Gen it had the usual Starmie Special Sweeper moveset: Thunderbolt - ELECTRIC Ice Beam - ICE Psychic - PSYCHIC Surf - WATER Of course, I had to take Surf off it to migrate it to the DS. And of course, they've changed Surf between the 3rd & 4th Gen: now, in a Double Battle, it hits your ally Pokemon as well as the two foes. This means I will be avoiding Surf in the future, because I like Double Battles, and the change screws up a lot of my strategies. So now I have to figure out a new 4th move, as well as deciding if I want to switch out any of the existing moves. Possibilities: TM03 Water Pulse - WATER, special - power 60, acc 100 - 20% chance of confusing the opponent. TM15 Hyper Beam - NORMAL, special - power 150, acc 90 - No thanks, two turn moves FTL. TM55 Brine - WATER, special - power 65, acc 100 - Power doubles if foe's HP is less than half. TM86 Grass Knot - GRASS, special - power ??, acc 100 - Power increases if foe is heavy. TM91 Flash Cannon - STEEL, special - power 80, acc 100 - 10% chance of lowering opponent's Special Defense by 1 stage. I think the only serious possibilities are Water Pulse, Brine and Flash Cannon. I don't like moves where I have to remember an entire table of data to know how effective they'll be (sure, I can remember that Steelix and Snorlax are heavy - the other ~400, not so much!), so that cancels out Grass Knot. What do you reckon: Water Pulse, Brine or Flash Cannon? Or Water Pulse/Brine and switch one of the other moves for Flash Cannon? Please give reasons - I've basically made the decision in my head and I want to know whether other people agree with me .
