Creatures are destroyed as a state primarily based motion (SBA) after they have deadly harm marked on them, often this implies at any time when they’ve harm equal to or larger than their toughness704.5g. SBAs are checked at any time when a participant would obtain precedence in a loop till no SBAs occur throughout a test704.3. Gamers obtain precedence on the finish of every fight harm step510.3, after harm has been dealt510.2 and any harm dealt is marked on the creature till the cleanup step of the ending section514.2.
Prevention results are a sort of steady impact615.1 that cease harm from occurring615.6 so long as they’re affecting the sport, until another capacity stops harm from being prevented615.12, like Questing Beast or Skullcrack.
In your query, all of this implies, sure a creature that has deadly harm on it on the finish of the primary strike fight harm step dies when SBAs are checked throughout that fight harm step, earlier than the second fight harm step begins, and any static skills that have been supplied by that creature, like Rescue Retriever harm prevention instantly finish, permitting creatures with out first strike to do harm to different troopers within the common fight harm step.
In contrast to your earlier query, the primary strike capacity is vital right here, as a result of the defending participant would want to dam the Retriever with sufficient first strike harm to kill it and finish the prevention impact. All first strike harm to different troopers is prevented, so these different troopers should be blocked by creatures with out first strike.
There isn’t any contradiction as a result of “this creature has taken harm, however due to a static toughness enhance, that harm was not sufficient to kill the creature until the toughness enhance ends or extra harm is dealt” and “this creature didn’t take any harm as a result of that harm was prevented” are very various things, eradicating the toughness enhance makes the harm already on the creature sufficient to kill it in your earlier query, however on this query the harm was prevented, the harm was by no means “marked” on these creatures, and eradicating the harm prevention impact doesn’t retroactively apply any harm that had already been prevented, it simply permits new harm to be dealt sooner or later.
510.2 Second, all fight harm that’s been assigned is dealt concurrently. This turn-based motion doesn’t use the stack. No participant has the possibility to forged spells or activate skills between the time fight harm is assigned and the time it’s dealt.
510.3 Third, the lively participant will get precedence. (See rule 117, “Timing and Precedence.”)
514.2 Second, the next actions occur concurrently: all harm marked on permanents (together with phased-out permanents) is eliminated and all “till finish of flip” and “this flip” results finish. This turn-based motion doesn’t use the stack.
615.1 Some steady results are prevention results. Like substitute results (see rule 614), prevention results apply constantly as occasions occur—they aren’t locked in forward of time. Such results look ahead to a harm occasion that will occur and fully or partially stop the harm that will be dealt. They act like “shields” round no matter they’re affecting.
615.6 If harm that will be dealt is prevented, it by no means occurs. A modified occasion might happen as an alternative, which can in flip set off skills. Word that the modified occasion might comprise directions that may’t be carried out, during which case the not possible instruction is solely ignored.
615.12 Some results state that harm “can’t be prevented.” If unpreventable harm could be dealt, any relevant prevention results are nonetheless utilized to it. These results gained’t stop any harm, however any extra results they’ve will happen. Current harm prevention shields gained’t be decreased by harm that may’t be prevented.
704.3 At any time when a participant would get precedence (see rule 117, “Timing and Precedence”), the sport checks for any of the listed circumstances for state-based actions, then performs all relevant state-based actions concurrently as a single occasion. If any state-based actions are carried out on account of a test, the test is repeated; in any other case all triggered skills which might be ready to be placed on the stack are placed on the stack, then the test is repeated. As soon as no extra state-based actions have been carried out as the results of a test and no triggered skills are ready to be placed on the stack, the suitable participant will get precedence. This course of additionally happens throughout the cleanup step (see rule 514), besides that if no state-based actions are carried out as the results of the step’s first test and no triggered skills are ready to be placed on the stack, then no participant will get precedence and the step ends.
704.5g If a creature has toughness larger than 0, it has harm marked on it, and the entire harm marked on it’s larger than or equal to its toughness, that creature has been dealt deadly harm and is destroyed. Regeneration can change this occasion.
