I sac my auras over and over and Bruna keeps bringing them back.
• Sacrifice Aura / Enchantment / Permanent as a cost
• Auras that sacrifice themselves (not too many of these)
• Whenever Aura / Enchantment enters the battlefield... triggers
This build isn't too concerned with having a Voltron Bruna out.
