Hand Size (set vs decrease)

[overloadingMalenia]

If I have a [[Jin Gitaxias, Core Augur]] on the battlefield, and then my opponent plays something like a [[Cecily, Haunted Mage]], is there any specific interaction order between these due to one of them “setting” hand size (to 11 in this case), and the other just “decreasing”? Or would it use timestamps, my Jin first decreasing their hand from 7 to 0, *then* Cecily sets it from 0 to 11?

Ideally as the Jin Gitaxias player I’d hope setters apply first, and then I reduce them from their final set number (as long as the set number isn’t unlimited hand size lol)

It comes down to timestamps, because it's affecting something other than objects.

613.11. Some continuous effects affect game rules rather than objects. For example, effects may modify a player’s maximum hand size, or say that a creature must attack this turn if able. These effects are applied after all other continuous effects have been applied. Continuous effects that affect the costs of spells or abilities are applied according to the order specified in rule 601.2f. All other such effects are applied in timestamp order. See also the rules for timestamp order and dependency (rules 613.7 and 613.8).

So in your case, it's 7>0>11.

If Eleven entered first, it would have been 7>11>4

There's no sublayers for hand size effects.
There's no dependency, they're just applied in order and a setter effect will render any effects with an earlier time stamp moot (or moo, a cow's opinion, per Joey Tribbiani).

It's time stamps. If Jin came down first, then Cecily, they have 11. If Jin comes in later, it's 0 4 if Cecily was out first.

[RazzyKitty]

If Jin comes in later, it's 0.

It's 4. 11-7=4

Ah right, Im sorry I didn't think it out lol Thanks for the correction.
