Do you understand how psychic powers are acquired?

According to the FAQ, tyranids may use the new discipline powers instead of their own.

Can they swap some of their powers, but not all?

With the exception of the swarmlord, all the psykers are mastery level 1, does that mean they can't use the 2 cost powers? Do you have any options if you happen to roll one of these abilities?

Thanks for any info you can share!

1) They have to swap all of thier powers or none.
2) Only the Swarmlord can use Warp Charge 2 powers. If you roll one with a Mastery 1 psyker you have to reroll.
3) If you get a power that you do not want you can default to the primaris power for the Discipline.
