Dustrider Pointman

Defender, nonbasic landwalk, reach
When Dustrider Pointman enters, if it's not
a token, create a token that's a copy of it if
an opponent sacrificed a land this turn. If it's
a token, it loses defender as it enters.
Whenever Dustrider Pointman deals combat
damage to a creature, without flying, that creature's controller sacrifices a land.
