(I Apologize if anyone else said this)
The Legendary Birds are named after Spanish Numbers (also know they are in order by the sp. number and poke num.) and Themed Places
#144 (Bird 1) Articuno > Artic (Ice) & Uno (1)
#145 (Bird 2) Zapdos > Zap (Shock) & Dos (2)
#146 (Bird 3) Moltres > Molt (Magma) & Thres (3)
Oh, this one seems classic from the Abra family:
Magician: ABRA, KADABRA, ALAKAZAM!!
