Ok here's the idea: Low CMC. Stupid amount of enchantments. Throw down small unblockable creatures or ones that benefit having lots of enchants. Aura them all up until Bruna is ready. Sphere of Safety
, or Fountain Watch
+ Enchanted Evening
to keep opponents focused on others. Self-mill and swing with Bruna. Jace Beleren
can make that big swing come on turn 7. Definitely a budget deck.
