Thuxrena, Mother of Fay

Creatures you control can't get negative counters.
Other creatures you control gain trample.
{2}{g}: target creature with control gets a +2/+2
counter. It gains Vigilance until end of turn.
If Thuxrena, Mother of Fay would be put into
the graveyard from anywhere, shuffle it back
into it's owner's library instead.
