When a land leaves the battlefield all creatures
you control gets Rampage 2 (Whenever this
creature becomes blocked, it gets +2/+2 until
end of turn for each creature blocking it beyond
the first.)and mana drain (when a creature
mana drains you may look at the top card
of your library and graveyard it if it was a

enters the battlefield)Until end of turn.
When they start running you cant stop them
