Can be used the turn you Special Summoned "Black Rose Dragon" when you control "Black Rose Dragon".Destroy all cards on the field. This Skill will not activate if you begin the Duel with a Deck that contains monsters other than Plant-Type monsters or "Rose Dragon" monsters. This skill can be used once per Duel.
Not really. You have to trigger this one the turn you summon BRD, and not any later in the game.
The skill says Special Summon rather than Synchro Summon, sou you could potentially use the effect twice in a Duel with a single BRD if you manage to get it back from the GY. Also, the bonus of not being able to be negated since it´s a skill. The restriction is quite steep, though.

Basically BRD but can't be negated by card effect.
