The Church of Exploration

{3}: Your deity searches their library for a land card, puts it into their hand, then shuffles their library. Put an Exploration counter on this. Only your worshipers may activate this ability.
At the beginning of your upkeep, if this has ten
or more exploration counters on it, remove three from it, and each of your worshipers searches their library for a land card, puts it onto the battlefield tapped, then shuffles their library.
