They had different backs and still arent legal for tournament play, but everyone I know who has these uses them for Cube or Commander

Two things bothered me about slapping the title 'Bootleg' on them though - the first being that they had all the correct official copyright info, with the addition of 'Licensed by TOP-IN', and the second being that the cards so proudly declared FUNSKOOL all over the card, even though the original Base Sets had nothing to do with Funskool at all
Most of them help the deck ramp mana, pay you off for having lands of a specific type, or assemble a critical mass of lands with a specific land type
Third, you'd normally play cards like these in order to jump ahead in mana, but you still want to play a land every turn, at least for the first few turns
