Also, the other level 4 spellcasters are there if I don't pull SM lv4 and level up first hand, using magicians circle lets me either pull a SM lv4 if I can level up it, or if I already have a lv8 on the field get extra monster back up with 2200 attack straight off the bat with yami on the field and dark magician girl. I was debating champions vigilance as extra lv8 protection
