In August of 2015, I suggested dumping the Eventide versions which had bottomed out at $7 at the time, and replacing them with $2 Modern Masters 2015 copies. This was good advice, as the MM2015 versions are about $2.50 now and the Eventide versions are about $4. However, vendors have been slowing increasing their buylists and some vendors are listing their copies near or over $5.
As it turns out, there is some sign of demand finally overtaking the supply. While I'm not sure this card hits $10 for a long time, $5 for the Modern Masters and some slightly higher number for the Eventide version isn't out of the question. If you might play this in Commander at some point, I'd pick up my copy soon.
