Creature â Human Spy
When Clocknapper enters the battlefield, choose beginning phase, precombat main phase, combat phase, postcombat main phase, or ending phase. Steal that phase from target player during their next turn. (That phase occurs as though it's your turn instead.)2/2
To steal a phase means that during that playerâ€™s next turn, as the chosen phase begins, you treat it as if it were your turn. Hereâ€™s what happens if you steal each phase:
Precombat main phase: You can cast all types of spells while your opponent can only cast instants and spells with flash.
Postcombat main phase: Same as precombat main phase.
Ending phase: Most abilities that trigger during the end step donâ€™t care whose turn it is, but a few do. Effects that last â€œuntil end of turnâ€ or â€œthis turnâ€ will expire as normal, as they also donâ€™t care whose turn it is.
Combat phase: Just like combat on your turn, you can attack your opponents with your creatures. The opponent you stole the phase from canâ€™t attack with their creatures, but they can block.
Beginning phase: You untap permanents you control and your opponent doesnâ€™t. Abilities that trigger at the beginning of your upkeep happen and ones that trigger at the beginning of their upkeep donâ€™t. You draw a card as itâ€™s now your draw step, so your opponent doesnâ€™t.
