Split Second and priority

[meatpipeline]

From the Comprehensive Rulebook:

408.1c The active player gets priority at the beginning of most phases and steps, after any game
actions are dealt with and abilities that trigger at the beginning of that phase or step go on the
stack. No player gets priority during the untap step and players usually don’t get priority during
the cleanup step (see rule 314.3). The player with priority may play a spell or ability, take a
special action, or pass. If he or she plays a spell or ability, or takes a special action, the player
again receives priority; otherwise, the next player in turn order receives priority. If all players
pass in succession (that is, if all players pass without taking any actions in between passing), the
top object on the stack resolves, then the active player receives priority. If the stack is empty
when all players pass in succession, the phase or step ends and the next one begins.


Am I correct in saying that I can cast a spell x, retain priority, and cast a split second spell... effectively making spell x uncounterable?  Could I also cast spell x, retain priority, instant y, retain priority, and cast a split second spell making x and y uncounterable?




Thanks,

Phil

You can cast something and then cast a split second spell in response before passing priority, however the split seconds spell wiill resolve first, and after it has resolved your opponent will be free to respond to your original spell(s), and thus can still counter it if they want to (split second only works while the spell with split second remains on the stacK).

If there was some way of putting the split second card below the other spell on the stack, then this would work. There might be such a way but I do not know of it.

If I'm not mistaken, you can make Morph triggers uncounterable by Stifle/Trickbind this way, can you not?

[Matt]

You can pay morph costs with a Split Second card on the stack, but they were already uncounterable since they are a special action and don't use the stack.

[diopter]

Oops, sorry. I meant the "when ~this~ is turned face up" triggers, which I always thought were counterable.

[Komatteru]

Morph doesn't use the stack, so it can't be Stifled.  You can Stifle any "When this is turned face up..." trigger.  However, it is correct that if you can get something to trigger while a Split Second spell is on the stack, then your opponent will not be able to Stifle that trigger.
