Uva, Primordial Perfection

When you cast this spell, each player reveals the
top three cards of their library. For each player,
choose a card to put into their hand and put the
rest into their graveyard. Put a number of +1/+1
counters equal to the total mana value of the
chosen cards divided among other creatures you
control.
Uva's power and toughness are each equal to the
number of +1/+1 counters on other creatures
you control.
