yes, your right.
Farseek puts it into play tapped, my mistake.
But i've just checked, you got no nonbasic Swamps, so
Rampant Growth might be an more flexible option (at least at the current state of the deck).
I've noticed the "upgrade me", that was my reason to give you some suggestions.
All in all i've already seen worse (and more expensive) meren decks here. I think you're on the right track.
