Satsuki and Mei, Sisters

When Satsuki and Mei enter the battlefield, each opponent may search their library for a basic land
and put it into play tapped then shuffle. For each opponent that does, you may search your library
for a basic land and put it into play, then shuffle.
Creatures you control gain +1/+1 if you control
the most lands. If you control five or more lands
than the player with second most amount of lands, prevent all damage dealt to creatures you control.
