8 rulings from Wizards of the Coast
- 12 April 2024The copy created by Stella Lee’s last ability will have the same targets as the spell it’s copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. The new targets must be legal.
- 12 April 2024The copy made by Stella Lee’s last ability is created on the stack, so it’s not “cast.”
- 12 April 2024You pay all costs and follow all normal timing rules for cards played from exile with Stella Lee’s first ability. For example, if the exiled card is a land card, you may play it only during your main phase while the stack is empty.
- 12 April 2024If the copied spell is modal (that is, it says “Choose one —” or the like), the copy will have the same mode or modes. You can’t choose different ones.
- 12 April 2024If a spell that’s copied has an X whose value was determined as it was cast, the copy will have the same value of X.
- 12 April 2024If the copied spell divides damage or distributes counters among a number of targets, the division and number of targets can’t be changed. If you choose new targets, you must choose the same number of targets.
- 12 April 2024You can’t choose to pay any additional costs for the copy. However, effects based on any additional costs that were paid for the original spell are copied as though those same costs were paid for the copy too.
- 12 April 2024Spells that were cast before Stella Lee entered the battlefield count. If Stella Lee was the first spell you cast this turn, the next spell you cast this turn is your second spell.
