Forum:Ruling chain help

I need help with chain rules. I am going to use a example to explain. So here goes:

My main phase, I summon Breaker the Magical Warrior use his effect to target my opponent's face down Waboku can he chain the same face down Waboku to Breaker's effect as a trap has a higher spell speed or is it that Waboku is chain link 0, Breaker chain link 1.
