The Thirteenth Doctor

2023-10-13 If a spell or ability allows you to copy a spell on the stack but doesn't specify that the spell is cast, that spell wasn't cast and won't be counted by paradox abilities.

2023-10-13 Paradox abilities count any spells cast from zones other than your hand. These are usually spells cast from exile, the graveyard, or the command zone. They also count spells cast from outside the game, such as spells cast with Wish or Garth One-Eye's ability.

2023-10-13 The Thirteenth Doctor's last ability untaps creatures you control with any kind of counter on them, not just creatures you control with +1/+1 counters on them.
