No trainers will have articuno.
I'm sorry, but articuno isn't in pokemon pearl, it's only in pokemon platinum (talking about the ds games)
In Pokemon Diamond, I found Articuno in Safari Zone, I just don't know if it works in Pokemon pearl, (Area 1)...
You can't catch articuno in pearl unless you migrate it from firered or leafgreen.
Tyson have a Munchlax on Pokemon Pearl
Unfortunately there is not.
