First, The Arrival of Trast

Whenever an Angel creature enters the
battlefield under your control, put a quest
counter on First, The Arrival of Trast.
If First, The Arrival of Trast has six or more
quest counters on it, sacrifice it and create
an X/X white Avatar creature token with
flying, where X is equal to the number of
Angel's you control.
Day I : I rest upon the shallow land.
