Ragnars Legacy

Whenever you put a Loot counter on a
permanent you control, put twice that many
Loot counters on it instead.
Whenever a creature you control attacks and if it
has at least one Loot counter on it, remove a
Loot counter. This creature gains Berserker until
end of turn (This creature attacks a creature an
opponent controls instead attacking him directly.).
At the end of your turn put a Loot counter on
any permanent you control.
