Autumn, Nature's Wrath
Autumn has indestructible if you control no other creatures and has no +1/+1 counters on it.
Whenever another creature enters the battlefield under your control, put a +1/+1 counter on each creature you control with shroud.
Remove a +1/+1 counter from Autumn: Autumn loses shroud, gets +1/+1 and gains trample until end of turn.
