[Phyrexian Swarmlord](http://gatherer.wizards.com/Pages/Search/Default.aspx?name=%2b%5bPhyrexian%20Swarmlord%5d)'s last ability is that you create infect tokens based on the number of poison counters on your opponents. Let's say I'm playing a 1v1v1 and I have him on the battlefield with opponent A having 2 poison counters and opponent B having 9, and I proliferate. If I choose player B's poison counters as part of my proliferate that player loses from having 10 poison counters, but as the game continues, would I still get 10 tokens from them where the player lost with that many counters on them? Or should I exclude them from proliferate as long as possible to continue getting 9 infect tokens because they need to be alive in the game to get the tokens?
