Armored White Bear can float into this card either from deck or graveyard. I think this is the viable way to make use of Constellar Meteor, until Komoney release more low level Constellar monster with decent stats
Actually the lv5 includes both normal & special summon. Which makes it worth the while.. also, setting ur board with two level 5 for xyz & getting a search for it is quite worthy.
Note: xyz are not out yet. We all know.
