need some help at map making

how do you make a starting point without getting the castle and all the peasants, and how do you make a hero selector and how do you get the hero to teleport to a certain location?

1) Delete the melee trigger that places starting units for each player.

2) What kind of hero selection system do you want to make? There are several effective ones.

3) There is a trigger action, Unit - Move Unit Instantly [sic]

you have a unit thats a selector and you can see several heroes lined up to choose from

Give the selector a single-target ability, like Storm Bolt.

Make a trigger that fires when a unit uses an ability.
Check to see if it's your dummy chooser ability.

Make one (Target unit of ability being cast) for (owner of (casting unit)).
Kill (casting unit).

That's pseudocode; ought to be enough to get you started on it.
