MTG Salvation

Ok, thanks.

Hi everyone, i already understand "Ninjutsu" mechanic, it is well explained in the cards with that skill. My doubts are about activated habilities from ninjas: All ninja cards says something like "do X when it makes combate damage to a player", it means i have to make combat damage directly to the life of that player for the hability to active? or when it says "to a player" is in a general way, so ninja habilities could be activated doing damage to that player creatures too? (then the habilities will active atacking, no matter you were blocked or not or even blocking with your ninja) I play casually with friends and untill now i understood "to a player" in the specific way, so i used ninja habilities when they enter in battlefield using ninjutsu mechanic, but once in battlefield my ninjas were pretty useless, cause most of them are weak and was very difficult make combat damage to the life counters of my opponent again. Then i thought maybe every combat damage will count, that way ninjas would be far better than i used them untill now. Im waiting for your answers please, cause i dont want to cheat my friends. Thanks. P.D.: Excuse my bad English, its not my mother language.
