Forum:Black Luster Soldier - Envoy of the Beginning questions

I have 2 questions about black luster soldier that I can't decide on with my friends.

1. If the summoning conditions are met and Black Luster Soldier is summoned then destroyed with a dark hole, black rose, etc., can it be re-summoned with monster reborn or call of the haunted even though it says "This card cannot be special summoned except by..."?

2. Can Black Luster Soldier attack multiple times if my opponent has multiple monsters on the field? for example, lets say my opponent has Stardust Dragon, Scrap Dragon, and Trishula on the field, can I attack all of them and then attack him directly or can I only attack 2 of them?
