Equivalent cards to Skyclave Cleric (white, enters-the-battlefield life gain, modal DFC land) are:

• Sejiri Shelter // Sejiri Glacier (white, modal DFC land, provides protection)
• Kabira Takedown // Kabira Plateau (white, modal DFC land, removal spell)

Reason: All are white modal double-faced cards (DFCs) from Zendikar Rising with utility spells on one side and Plains-producing lands on the other.

No other card has the exact ETB lifegain modal effect, but these are close white equivalents in the same set/mechanic.
