Parley — Whenever Innocuous Researcher attacks, each player reveals the top card of their library. For each nonland card revealed this way, you investigate (To investigate, create a colorless Clue token. It's an artifact with ", Sacrifice this artifact: Draw a card."). Then each player draws a card. At the beginning of your end step, you may untap all lands you control. If you do, you can't cast spells until your next turn.
