Some weird questions about SBAs
Asked by chosenone124 6 years ago
I control March of the Machines, Mycosynth Lattice, and Akroma's Memorial.
I know that playing lands doesn't use the stack or pass priority. Does that mean I can play a land and tap it for mana before the game checks SBAs and puts the land in the graveyard?
If I control the above 3 permanents and a Viscera Seer. can I play a land and sacrifice it to the Seer?

No, you won't be able to do anything else with the land. The game will check SBAs before you're given priority again. Here's the most relevant rule from the CR:
116.3c If a player has priority when he or she casts a spell, activates an ability, or takes a special action, that player receives priority afterward.
Due to this and other related rules in Section 116, "Timing and Priority", we get the result that no player has priority in the middle of someone doing something, only before and after. The game processes SBAs right before each time a player would get priority for any reason, and that includes special actions that don't use the stack

115.2a Playing a land is a special action. To play a land, a player puts that land onto the battlefield from the zone it was in (usually that players hand). By default, a player can take this action only once during each of his or her turns. A player can take this action any time he or she has priority and the stack is empty during a main phase of his or her turn.
115.3. If a player takes a special action, that player receives priority afterward.
704.3. Whenever a player would get priority (see rule 116, Timing and Priority), the game checks for any of the listed conditions for state-based actions, then performs all applicable state-based actions simultaneously as a single event. If any state-based actions are performed as a result of a check, the check is repeated; otherwise all triggered abilities that are waiting to be put on the stack are put on the stack, then the check is repeated. Once no more state-based actions have been performed as the result of a check and no triggered abilities are waiting to be put on the stack, the appropriate player gets priority. This process also occurs during the cleanup step (see rule 514), except that if no state-based actions are performed as the result of the steps first check and no triggered abilities are waiting to be put on the stack, then no player gets priority and the step ends.
605.3a A player may activate an activated mana ability whenever he or she has priority, whenever he or she is casting a spell or activating an ability that requires a mana payment, or whenever a rule or effect asks for a mana payment, even if its in the middle of casting or resolving a spell or activating or resolving an ability.
I'm pretty sure these are all of the relevant rules to the situation here.
Based on these rules, it would seem like as soon as you play a land the game checks for SBAs before you receive priority again, and the land would die before it can be tapped for mana or sacrificed to an activated ability, because you can only do those things if you have priority, or meet one of the other conditions for mana abilities.
