For those of you that haven't noticed this card:

Forbidden Orchard -
Land
T: Add one mana of any color to your mana pool.
Target opponent puts a 1/1 colorless Spirit creature token into play.
Rare

Now - what do we have here? - A gemstone mine that doesn't deplete.  In Type 1, giving the opponent a 1/1 colorless dude is NOT a drawback.  Most combodecks would want to play this card over Gemstone Mine any day, since it doesn't die du to overuse.  While it may be a slowpained city of brass (since you probably can't block), it's immidiate "I lose the life in your turn instead" might prove useful to combodecks based on Bargain. On the other hand, will this card bring back the Oath? All of a sudden, we have an uncounterable way to hand the opponent a dork that won't do him any good against the might of Morphling/Colossus.
In my world, SapphireOath might make a small impact on the metagame. Since I'm European and not german/dutch, the players with full power is about than 10-15% of the meta. This doesn't mean that Oath shouldn't see play in highpower meta's. Since more and more controldecks run solid creatures as their kill, I don't see why Oath shouldn't be played.
Especially when we have a new way to give that keeperplayer an unwanted token. Oath, and especially SapphireOath have always relied on  it's sideboard to handle the controlmirror - This will have to be the exception rather than the rule, should Oath reappear on the scene.  
It should be possible to build a strong UBG Oath deck on the Hulk base, opting to kill slowly, but way more reliable than with a 1/2 guy. It doesn't even need to cast it's wincondtion, moving the counterwars from a REB-able-card, to a green enchantment.

I need your thoughts.
