How about,

• Canopy Cover instead of one of you instants. not only does it protect your creature from all spells except AOE spells it also protects your creatures from abilities.

Thanks for the suggestion! I'll try using 2 Canopy Cover instead of 2 Ranger's Guile for right now. The reason I picked Ranger's Guile was because it was only one mana, but I'll try out Canopy Cover.

I would think that some kind of regen effect is necessary for mass removal? I mean, nothing helps with a Golgari Charm or something, but you could avoid a Pyroclasm or Volcanic Fallout with some kind of mass regen effect...

Consider Brave the Elements over Luminesce for protection against burn (or anything for that matter).

Brave the Elements only protects white creatures which won't save most of the creatures or tokens, you could use Gods Willing. I'd suggest Mark of Asylum, and maybe even Burrenton Forge-Tender for the sideboard.
