#5 - Why, the ________________

This card does not untap during your untap step.
When this card enters the battlefield, put a verse
counter on target creature without a verse
counter on it. For as long as that creature has a
verse counter on it, it has "You may remove a
verse counter from this creature: it gets +2/+2
until end of turn." (The verse counter continues
to work after this card has left the battlefield.)
{5}{g/u}: Exile this card until the beginning
of the next end step.
