Milu and Toba, Shrine Keepers

You may reveal this card from your opening
hand. If you do, search your library for a monocolored Shrine card and put it onto the battlefield tapped, then shuffle.
Whenever a Shrine enters the battlefield under
your control, you draw a card and gain 3 life.
This ability triggers only once each turn.
The "legend rule" doesn't apply to Shrine
permanents you control.
