Im going to organize them in rough categories by price, starting with the bad pulls: Bulk Foils ($0.25 $3) Springjack Shepherd $0.25 Greater Mossdog $0.25 Ogre Gatecrasher $0.25 Chimney Imp $0.50 Council Guardian $0.50 Noggle Bandit $0.50 Hornet Sting $0.50 Rescue from the Underworld $0.50 White Knight $0.75 Guerrilla Tactics $1 Iron Myr $1 Lumithread Field $1 Stalking Stones $1 Game-Trail Changeling $2 Maro $2 Mirrodins Core $2 Rhox $2 Celestial Dawn $3 Changeling Hero $3 Lapse of Certainty $3 Storm Crow $3 These 21 cards arent worth anything now, and that certainly wont change after the reprints
That said, having one or two of these in your deck smoothes things out and makes splashing easier, especially in slower formats where you have time to use them
They usually have a way to transform to their other face
The shock lands will hold value for years to come, as long as people are playing competitive Magic, and the serialized cards are always valuable, especially if you get one of those cool numbers like 069/500 or 420/500 (if you pull one of these, please let me know)
The condition doesn't play much of a factor yet, with near-mint (NM) cards readily available for sale from as low as ten cents to as much as 90 cents, with a lightly played (LP) sale thrown in around the 20-cent mark
