Combined with any Village, on two turns, Silver is a Laboratory, and Gold is a card that would probably cost $8 normally.
Even without a Village, suddenly every green card is useful, and chances are you will draw a ton.
It's a mini-Chancellor, and on your first Implosion-Duration turn, you're guaranteed to draw three Estates to buy a fourth. Future Implosion turns, guaranteed four Estates to get another Implosion, then some $4 and higher cards.
Open Silver/Implosion. Grab a couple Estates and either another Silver or a *Village. Yet another "race" card.
Guaranteed $3-plus cash on the Duration turn, Village has a chance of doing that two turns in a row, mini-Chancellor so you play it most turns, race conditions. $5 at least.
