Thanks for the comments. I just got my playset of Doubling Seasons today so I'm excited to put the finishing touches on this deck.
@Kirby002 - I am leery of putting creature enchantments in this deck because they are very fragile, making a juicy target for 2 for 1 removal. Now general enchantments could be good but I'm already running the four Doubling Seasons, I don't want to give up more slots in this deck for enchantments. BTW the way I'm growing the creatures is with
Mirror Entity, which is just a surprise power house! Read the card and realize the deck was built around it.
