Sigitri's Presence

When Sigitri's Presence enters the battlefield
search your library for up to three basic lands
and/or deserts, then you may put any deserts
searched for this way onto the battlefield tapped otherwise put them into your hand.
{1}{g}: Sacrifice target land you control and
draw a card if the sacrificed land was a desert
draw two cards instead.
