I know its better to have multiples of one type a card then 1 of about 20 different ones, but this these are the best I can do with my so very little options. Blue/Red uses the torrent of fire/Scornful Egotist while either killing off the other creatures with spark spray or fiery temper. Black/green uses the gempalms/shepherd of rot, while trying to kill using creatures. Please help me choose between these two decks.
