Fire Splitters

Whenever a Player taps a Forest, put a Burn
counter on it. When a Forest has one Burn
counter, it loses all other abilities and and
gain "{t}: Add {1}". When a Forest has two
or more Burn counters, its controller
sacrifices it. When a Forest is send to an
opponents graveyard, create a token copy
of Fire Splitters. Burn counters can't be
proliferated.
