Planechase 2012: Savage Auras

You could enhance a creature that has an evasion ability, like Armored Griffin (which also has vigilance) or Silhana Ledgewalker (which also has hexproof), and go on the offensive. Alternately, you could select a creature that's flat-out asking to be enchanted. Bramble Elemental and Dreampod Druid both provide Saproling tokens if enchanted, and an enchanted Krond the Dawn-Clad exiles a permanent each time it attacks! Meanwhile, Celestial Ancient and Sigil of the Empty Throne give you a bonus each time you cast an enchantment spell, and Auramancer and Dowsing Shaman recover enchantment cards from your graveyard. As long as you're building nearly invulnerable supercreatures, you might as well get rewarded for your efforts!
