Shyshrut, Crux of Creation

At the beginning of each upkeep, create a 0/1
green Plant creature token.
At the beginning of your end step, you may
sacrifice any number of Plants you control. For
each creature sacrificed this way, choose one
that has not been chosen yet this turn:
• Draw a card.
• Put a land from your hand into play tapped.
• You gain 4 life.
