At the beginning of your upkeep, you may put a verse counter on Discordant Dirge.
, Sacrifice Discordant Dirge: Look at target opponent's hand and choose up to X cards from it, where X is the number of verse counters on Discordant Dirge. That player discards those cards.
Adding a counter is optional. If you forget to add one during your upkeep, you cannot back up and add one later.
