Mishra's Factory under new rules

[Hanni]

Just a quick question. I'm pretty sure I know the answer, and that's how my opponent and I played it out, but I wanna get the correct ruling anyway.

I know Mogg Fanatic can no longer do the block, stack, sac effect.

However, this is different with Factory, correct? If my opponent attacks with a 3/3 Mongoose, I block with Factory, I can still activate it's pump and make it 3/3 before damage goes on the stack, trading my Factory with their Goose. Correct?

Of course, you still get to playing instants after blockers are declared and before damage dealt, you just skip the "damage on the stack" part of combat.

You get priority after blockers, same as always.


509. Declare Blockers Step

509.1. First, the defending player declares blockers. This turn-based action doesn't use the stack. To declare blockers, the defending player follows the steps below, in order. If at any point during the declaration of blockers, the defending player is unable to comply with any of the steps listed below, the declaration was illegal; the game returns to the moment before the declaration (see rule 714, "Handling Illegal Actions").

509.2. Second, for each attacking creature that's become blocked by multiple creatures, the active player announces its damage assignment order among the blocking creatures. This turn-based action doesn't use the stack. (During the combat damage step, an attacking creature can't assign combat damage to a creature that's blocking it unless each creature ahead of that blocking creature in its order is assigned lethal damage.)

509.3. Third, for each creature that's blocking multiple creatures (because some effect allows it to), the defending player announces its damage assignment order among the attacking creatures. This turn-based action doesn't use the stack. (During the combat damage step, a blocking creature can't assign combat damage to a creature it's blocking unless each creature ahead of that blocked creature in its order is assigned lethal damage.)

509.4. Fourth, any abilities that triggered on blockers being declared go on the stack. (See rule 603, "Handling Triggered Abilities.")

509.5. Fifth, the active player gets priority. Players may cast spells and activate abilities.
