[ Card Games ] Open Question : MTG: Casual play G/U Snake deck, advice? [Non-kamigawa]?

I feel like my deck is pretty perfect so far, but I would of course love advice for it. It seems to do terribly against casual artifacts with you know, mirrodin.. Not that I play against it much, tho. Enchantments: Snake Umbra x4 Canopy Cover x4 Spreading Seas x3 Creatures: Lorescale Coatl x4 Winged Coatl x4 River Boa x 4 Instants: Snakeform x4 Sorceries: Distortion Strike x4 Divination x3 Mind Spring x2 Land: Island x10 Forest x10 Yavimaya Coast x4 Basically centered around Lorescale Coatl, pumping him up with Snake Umbra and gaining cards from an unblockable hit from Distortion Strike. Mind Spring and Divination draw straight-up, giving the snake more bonuses. River Boa is a good two-drop just in case I don't touch my Coatls til later in the game, and is really more of a filler that I can still pump with enchantments/unblockable, with the use of Spreading Seas. Things like Snakeform and Winged Coatl are there for heavy-hitting creatures to include flying. Sideboard: Wing Puncture x4 Death-hood Cobra x4 Cobra Trap x4 Steel Sabotage x3 Where I play, I've been seeing a LOT of unfair artifacts with protection from everything under the sun-- I can easily counter the heavy swords with Steel Sabotage, replacing Spreading Seas. Against heavy enchantment-targeting decks I slide Cobra traps for fun token snakes. Against flying, Wing Puncture pits my huge snakes against flying cards and kills them off easily. Both Cobra Trap and Wing Puncture would replace any number of Canopy Cover, depending. Lastly, Death-hood Cobra is a bit of a new addition, to replace River Boa if I took out Spreading Seas, or I still needed artillery against heavy-hitting creatures, to touch with flying/deathtouch/both, however I see fit. Any advice is welcome on how to improve. I hope you enjoyed my deck. :]
