So four colorless mana for a 2/2 and a land is already ahead of the value curve by dodging a color restriction, and then it has the possibility of doing some damage, preventing some damage, and drawing another card when it dies
Tokens While lands eat up most of an Un-set's value thanks to the fact that they are some of the only tournament-legal cards in the set, one other group of cards from Un-sets is technically tournament legal: the tokens
(They can't be blocked as long as defending player controls an Island.)
