Hey check my post rotation deck Nylea mana ramp but this is nice +1 from me

If you are looking to buy Courser of Kruphix i would highly recommend considering purchasing the M15 Clash Pack , it comes with 1x Courser of Kruphix as well as 1x Genesis Hydra and 1x Nykthos, Shrine to Nyx as well as some other lesser cost rares. It also comes with 6 promo cards that have sweet alternative art including Prophet of Kruphix and Temple of Mystery . The MSRG is $30 but if you shop around online probably get it for less than $20.

Nice deck.

Archetype of Imagination it will be a win con with that field of hydras. Just use it when you have enough to finish the game and swing past anything your opponent has to offer.

Soul of New Phyrexia saves you from removal other than exile as you can keep mana open with prophet of kruphix and the soul will give you a constant indestructible barrier against your opponent.
