Earth

Reveal Earth outside the game: Put it on the
battlefield. Activate only at the start of the game.
All Methane Counters that would be added to
the World Supply are place on Earth instead.
At the beginning of each endstep, for every 2
Methane Counters, put a -0/-1 counter on a
creature chosen at random. For every 3 Methane Counters, deal 1 damage to each player with the
most Islands.
