Glistener Elf dies, Young Wolf receives a -1/-1 token. This, if I'm not mistaken, cancels out the +1/+1 token and the Young Wolf is now presumed not to have any counters on it. Does this mean that if I attack with another Glistener Elf and Young Wolf blocks, its undying ability will trigger again and cause the Young Wolf creature to come back a second time?
(For future visitors: I found a related question explaining why lethal infect damage wouldn't retrigger the ability a second time. My question is about non-lethal infect damage.)
