Elemental Invasion

Each opponent exiles all Artifacts and Instants from
their command zones, hands, libraries, battlefields,
and graveyards. They shuffle their libraries after.

Until the end of the game, up to three lands you
control are also 5/5 Elemental creatures with
Indestructible and Reach, and whenever an
opponent attacks you, they must pay {2}, or you
gain 2 life, for each creature attacking you.
