Dastara, Dryad Matriarch

Whenever a land enters the battlefield under your opponent's control, create a 0/1 green Dryad
creature token with reach.
{3}{g}: Each player searches their library for a
basic land card, reveals that card, then puts it
onto the battlefield under their control. Activate
this ability only once each turn.
"You ask why the forest is so cruel? You are even more stupid then I thought."
