Vivien’s arrow

When Vivien’s arrow enters the battlefield, flip target creature you control, then search your library for a forest and put it onto the battlefield.
Flipped creatures you control have +3/+4 and “when a forest enters the battlefield under your control, put a +1/+1 counter on target creature you control.
“My arrows fly as true as true as the fact the sun rises every day”-Vivien Reid
