Another need for clearing up an issue; Lets say I attack with Master of Diversion. I declare him as an attacker. His ability states that when he attacks I get to tap a target creature a defending player controls. First question: Does this happen before or after he declares his blocking creatures. Second question: when I tap one of his creatures, do I treat this creature as if he were attacking me and have to deal with his attacking value (i.e.: I tap his Silent Artisan 3/5 which effectively removes him from blocking, however does this mean that I have to either block that 3 damge or risk it damaging me).
