Land fetch and card drawing for one mana is too much. Even though the card is restricted to a forest, drawing one of these can make a one mana start viable. For a more balanced cost structure, take the following cards into consideration: Afflict, Aggressive Urge, Altar's Reap. Out of all your "Powder" cards, this one is the most overpowered.
I see your point. Thanks for the feedback. How about:Sprout PowderGInstantReveal the top card of your library. If it's a basic forest, put it onto the battlefield tapped. Otherwise, draw a card.
Yes, that is much better.
