Shimmering Hippocamp

Constellation — Whenever Shimmering
Hippocamp or another Enchantment
enters the battlefield under your control,
reveal the top X cards of your library,
where X is your devotion to blue. Put up
to one of them into your hand and the rest
on the bottom of your library in any order.
If you put a card into your hand this way,
you can't cast spells this turn.
