What I've learned from Articuno raids:
1. Takes at LEAST 8 to take down
2. Only 2% catch rate (so that means, only one out of those 8 players will be able to catch when beat)
3. It is usually the first person to just throw their ball out there, no berry, no curve, just a throw to catch it what wedding apparels to wear for 2nd wedding bride
4. Sucks! Because I went to three today, ALL wins and no Articuno
