Oppressive Decree

When Oppressive Decree comes into play, you may copy and trigger each Tribute ability of permanents you control. If you do,
pay {r/w}{r/w}{r/w} for each Tribute copied.
Tribute abilities are copied when triggered for permanents entering your battlefield or cast from your hand. Pay {r/w}{r/w}{r/w} for each Tribute copied.
