A few questions

[scizandor04]

1. If I use sketch with smeargle to get a move, then can I breed that move onto other field group pokemon? (assuming it is one of their egg moves) YES
2. In a 2 on 2 battle, do shadow tag and arena trap affect both pokemon, or only one?
3. If you encore a move in 2 on 2, does the opponent still choose their target or is it the pokemon they used the encored move on the first time?
4. What is the lowest HP IV Mewtwo can have to have 404 hp with max HP EVs? 19
5. Does macho brace multiply EVs but 1.5 or 2? I've seen both mentioned many times.
6. This one isn't a question, but what do you think of a sunbeaming ludicolo? it gets fire punch, solarbeam, synthesis, (no chlorophyll, though), and isn't weak to fire attacks. Any opinions?

Please post if you have the answers to any of these questions. :D Thanks a lot :)

for the Smeargle question: If Smeargle sketches a move, [s]he can breed with something to make a baby.

Example: Your Kadabra finds and uses Psybeam on a wild Male Smeagle. That Smeargle sketches Psybeam. Later in that battle, you catch the Smeargle. Then, you breed that Smeargle with a Female Masquerian. Eventually, you hatch your new baby Surskit and it knows Psybeam.

You could just breed a Male Dustox w/ Surskit/Masquerian, since theyre compatible and Dustox learns Psybeam at lvl24.

Awesome. The main reason I wanted that was for Sandslash :D He gets such a diversity of egg moves, which are almost impossible to learn together.

And using a new calculator I found, I figured out that the answer to teh mewtwo question is 19, which is a lot lower than I though (I was thinking mayve 29 :P I was wrong)

2. In a 2 on 2 battle, do shadow tag and arena trap affect both pokemon, or only one? Both, but Arena Trap doesn't affect Flying-types or Pokémon with Levitate.
3. If you encore a move in 2 on 2, does the opponent still choose their target or is it the pokemon they used the encored move on the first time? I'm not sure, but I'd assume that the Encore user would always be the target.
5. Does macho brace multiply EVs but 1.5 or 2? I've seen both mentioned many times. It doubles the EVs you earn.
6. This one isn't a question, but what do you think of a sunbeaming ludicolo? it gets fire punch, solarbeam, synthesis, (no chlorophyll, though), and isn't weak to fire attacks. Any opinions? It could work. The major upside to that is that he's not weak to Fire attacks.

Please post if you have the answers to any of these questions. :D Thanks a lot :)
I hope I helped.

yeah, Sunbeaming Ludicolo would work. I'd rather use something that gets Chloryphll, but this still works. I've been wanting to make a Sunny Day team, thanks for providing another pokemon besides groudon, fires, and a couple plain grass and grass/poisons.

And Encore, I think, affects the last opponent that made a move. Not too sure, so don't quote me on that
