So, while I was working on my Eevee team, a number of questions came up in regards to the effects, base powers, and other features of moves in the game.

First, Assurance. In a singles battle, if Assurance goes second, can it's Base Power be doubled (as per it's effect) by colateral damage incurred from recoil or confusion?

Second, Attract. Here's the situation: a male Pokemon uses Attract on a female Pokemon. The male uses Baton Pass to then transfer other improvements to another Pokemon. If the incoming Pokemon is a female, does Attract still carry over?

Third, Natural Gift. What berries have what effect on this move? Anything worth while?

Fourth, Trump Card. What are the Base Power numbers of Trump Card through it's 5 PP stages of attack?

Thanks muchly for the help on these!
