It's da best non-creature card.
Currently been messing around with mono colour control decks using this as a main engine (White being the only one I can really call serious, but still).
Engine I've been using is:
3 Trading Post
4 Ichor Wellspring
4 Pristine Talisman
1 Mycosynth Wellspring
3 Solemn Simulacrum
2 Wurmcoil Engine
3 Buried Ruin
3 Phyrexia's Core
From my own experience it works wonders in getting the engine to perform at its best. Also, controlling Trading Post and Wurmcoil, provided you have discard fodder can make you almost impossible to kill late-game.
