- WotCJul 12, 2019
Because the upkeep step is before the draw step, you discard for Rotting Regisaur’s triggered ability before you draw a card for your turn.
- WotCJul 12, 2019
If you have no cards in hand when Rotting Regisaur’s triggered ability resolves, you simply don’t discard any cards. There’s no penalty for being unable to do so.
