Santa Clause

Let the wait begin - On your end step create a 1/1
Elf creature with "at the beginning of each upkeep
except yours put a +1/+1 counter on this creature,
then on your upkeep put all +1/+1 counters on this creature on a creature an opponent controls."
Christmas Day- At the beginning of your upkeep
each player searches their library for a basic land
and puts it onto the battlefield tapped then
draws a card.
