Okay a question on the races things. Certain Races are emboidments of mana (Angels, White. Demons, Black) while others can actually be huge and yet still be walkers (Dragons come to mind). So may I ask what races are off the table if any because it wouldn't make sense for say... a spirit walker (besides the immensely powerful ugin) to planeswalk. Because really if any race is allowed it kinda heavily warps the multiverses logic of mana. Likewise what about 'Creature' Spells?
