I've read:

My question is about effects which occur when a creature "blocks or is blocked by" another creature, but regeneration is in the mix.

Specifically, I'm looking at Venom plus Regeneration. I know that regenerating a creature removes it from combat, and I know if the regenerated creature had been assigned as a blocker, the creature it blocked remains blocked after regeneration (i.e. it doesn't damage the defending player unless it has trample).

But, does the blocked creature remain blocked by the regenerated creature such that Venom's ability will trigger? Or in the other direction, if I attack with a creature using Venom and Regeneration, if I regenerate it would the blocking creature(s) still be destroyed?

Follow-up: If the answer is "no" I would imagine that Venom plus Elvish Scout (plus Lure or Tempting Licid) would still work to destroy all blockers, since Elvish Scout doesn't mention removing from combat, only untapping...or does untapping remove from combat anyway? Would vigilance make the combo work?

Let's look at Venom's Oracle text, because that makes this a little easier to understand:

Whenever enchanted creature blocks or becomes blocked by a non-Wall creature, destroy the other creature at end of combat.

That text sets up a delayed triggered ability.

603.7. An effect may create a delayed triggered ability that can do something at a later time. A delayed triggered ability will contain “when,” “whenever,” or “at,” although that word won’t usually begin the ability.

The delayed trigger for Venom is "at the end of combat" so when the end of combat happens, you destroy the creature that blocked the one enchanted with Venom.

603.7b A delayed triggered ability will trigger only once—the next time its trigger event occurs—unless it has a stated duration, such as “this turn.” If its trigger event occurs more than once simultaneously and the ability doesn’t have a stated duration, the controller of the delayed triggered ability chooses which event causes the ability to trigger.

Venom's ability doesn't state that the creature being destroyed must be a blocking creature, so it doesn't matter if it left combat (because of regeneration or otherwise). Even if it did, it wouldn't matter because of rule 603.7c:

603.7c A delayed triggered ability that refers to a particular object still affects it even if the object changes characteristics. However, if that object is no longer in the zone it’s expected to be in at the time the delayed triggered ability resolves, the ability won’t affect it. (Note that if that object left that zone and then returned, it’s a new object and thus won’t be affected. See rule 400.7.)

Example: An ability that reads “Exile this creature at the beginning of the next end step” will exile the permanent even if it’s no longer a creature during the next end step. However, it won’t do anything if the permanent left the battlefield before then.

So the short answer to your question is, as soon as the blocking happens, the other creature is going to be destroyed at the end of combat regardless of if it leaves combat. Regenerating before the end of combat will not save it from being destroyed (an additional regeneration can save it from the delayed trigger's destroy effect though). And yes, using something like Elvish Scout + Lure + Venom is a good way to make a one sided board wipe.

Also look at the rulings on Cockatrice (https://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=108912) to see a similar type ruling about needing to possibly regenerate twice to survive combat.

  • Thanks for the very thorough answer! Elvish Scout, Lure, Tempting Licid, Venom, Regeneration, and Elvish Berserker (in various quantities according to how many I happen to have) make an excellent mix for my Elf deck; I appreciate the confirmation about Elvish Scout working as I expect.

Venom triggers immediately on block and marks the blocking/blocked creatures for destruction. It will destroy all those creatures even if they left combat before the actual end of combat. Besides Venom not caring abouth whether the creatures are still blocking/blocked, the end of combat step removes all creatures from combat anyway, before Venom can resolve, so removing them from combat earlier can make no difference to Venom.

Venom creates a delayed triggered ability:

603.7. An effect may create a delayed triggered ability that can do something at a later time. A delayed triggered ability will contain “when,” “whenever,” or “at,” although that word won’t usually begin the ability.

The ability will trigger at the end of combat. However, by the time it goes on the stack and before it can resolve, all creatures are removed from combat anyway, so the creatures being in combat or not can not have an effect on Venom working or not. And either way, Venom does not state that the creatures have to be in combat in order to be destroyed, so it doesn't matter in the first place.

511.2. Abilities that trigger “at end of combat” trigger as the end of combat step begins. Effects that last “until end of combat” expire at the end of the combat phase.

511.3. As soon as the end of combat step ends, all creatures and planeswalkers are removed from combat. After the end of combat step ends, the combat phase is over and the postcombat main phase begins (see rule 505).

So Venom triggers at 511.2, and enters the stack only when players get priority at the start of the post-combat main phase. By that time, all creatures are removed from combat anyway.
