Blowfly Infestation Discussion

Rhadamanthus on Infinite Tokens, or Board Wipe?

2 days ago

This is similar to another question that came up a few weeks ago and it looks like my response to that one would still be relevant here. Let me know if there's some detail I missed that changes things.

There's a way to avoid an infinite loop, and according to the rules of the game you have to take that option at some point in the process. A loop made up of only mandatory actions will draw the game, but if there are any choices you can make to end it then you have to pick a number of iterations and make the different choice that will cause the loop to end after that point.

Let's say a creature with some number of -1/-1 counters dies and triggers the Blowfly Infestations. You target another creature with the triggers. For the sake of simplicity the following explanation assumes you target the same creature with the Infestation triggers, but it'll be pretty much the same situation if you target different creatures instead.

  • When the Infestation triggers resolve and place -1/-1 counters on the targeted creature, it triggers Nest of Scarabs, but it's not time to put the Nest trigger on the stack yet
  • State-based-actions (SBAs) are checked right before each time a player would get priority. The game sees a creature with 0 toughness and puts it into the graveyard, triggering the Infestations again. Similarly, these triggers aren't on the stack yet
  • When an ability triggers, it's put onto the stack the next time a player gets priority. If multiple triggers controlled by the same player are trying to go onto the stack at the same time, that player chooses what order to put them onto the stack. In this case you need to put the Nest trigger on bottom and the Infestation triggers on top. This is also when you choose a target for the Infestation triggers (some other creature on the battlefield)
  • Let the Infestation triggers resolve, and it sets off the same series of events described above. Now you have 2 Nest triggers on the bottom of the stack and another 2 Infestation triggers on top
  • Eventually you'll run out of creatures to target and kill with Blowfly Infestation, so it will stop adding triggers to the stack. All of the Nest of Scarabs triggers you've accumulated can finally start to resolve and will create the appropriate number of Insect tokens

If you need to keep the chain going for a while to kill more things then you can put the Nest triggers on the top of the stack instead in point 3 above, then they'll be available to target later.

Note that if two Infestation triggers target the same creature and the first resolving one kills it, we don't have to worry about the other one still hanging out there because it will get countered for lack of a legal target when we finally get around to processing it.

You can, however, target the same insect with both Blowfly Infestation triggers. Because the insect will be dead the second trigger won't resolve and you will only make 1 new insect off of Nest of Scarabs and only trigger the Blowfly Infestations 1 more time each. I believe you'll still end up constantly putting more triggers on the stack and compelling a draw though.

"would I then get infinite insects by being able to place the -1/-1 counters on the insect at the same time"

You can't place them "at the same time". Each Blowfly Infestation triggers separately, and resolves separately. Even should both target the same 1/1, after the first resolves, the 1/1 will die before the second one can resolve.

If you had two Nest of Scarabs and one Blowfly Infestation, then it would be a different story.

AkrosTheClear on Infinite Tokens, or Board Wipe?

In my deck Death's Creep I run some pretty fun and interesting combos that are mostly generated by Blowfly Infestation. With one of these out on the battlefield I can go infinite very quickly, but I have no idea what would happen if I had two. Every time a 1/1 insect or snake would die I would have to put two -1/-1 counters on up to two target creatures. For example, I have two Blowfly Infestations and a Nest of Scarabs out on the battlefield. Something with a -1/-1 counter on it dies and I get an insect, would I then get infinite insects by being able to place the -1/-1 counters on the insect at the same time, thus trading one insect of two, or would I wipe the board and lose the game by getting into an infinite loop with no end? I guess my question boils down to: can I put more than one -1/-1 counters from Blowfly Infestation's on a 1/1 creature? okay thanks for taking a look, that got pretty long.

Love the theme dude, very flavorful +1. Still I would try to utilize your commanders ability to a point that it gives you a big advantage.

For example:

Even though these cards are less flavorful, they give your commander more purpose and it also creates a secondary theme to the deck.

I would also go more with a control set up for this deck but that's a matter of opinion I guess. I would definitely run these:

Last note, proliferate is really good with your commander, you can abuse it easily with the cards I've enlisted above.

Still love your theme and the concept, this is only how I would tweak the deck.

The deck doesn't really compliment the commander. I understand it's just what you had on hand, but some good ideas are Nest of Scarabs Blowfly Infestation

dreamweaver6515 on Monoblack -1/-1 Scarabs Spam

Fun stuff, I always thought -1/-1 counters were a little underrated in Modern. My main suggestion would be adding Blowfly Infestation, they combo with Nest of Scarabs to give you infinite -1/-1 counters to throw around. (Though Blowfly is a bit expensive these days, so it depends on your budget).

So, I like the new build. Very stream lined. I would take out the red duel land, as it comes into play tapped and slows you down. Less plains also.

Maybe also play a few games trying:

Blowfly Infestation

Plague Belcher

Blood Artist

Zulaport Cutthroat

Grasping Dunes

Exemplar of Strength

Channeler Initiate

Contagion Clasp
