Haikouichthys, First Fish

When Haikouichthys enters the battlefield, if there
are no other creatures on the battlefield, place a
+1/+1 counter on it.

If the Era is Cambrian, and Haikouichthys would
be sent into your graveyard from anywhere, shuffle
it into your deck instead.

{t}: {u}{u} Activate only if Haikouichthys has a power greater than 0.
