Hi. Can I use the -1/-1 counter from Contagion Clasp to remove a +1/+1 counter from my Strangleroot Geist? I think +1/+1 counter and a -1/-1 counter would cancel each other out. But just want to be sure, so I asked here.
If those are the only relevant factors then yes you may use the contagion clasp to put a -1/-1 counter on Strangleroot geist and have SBA remove both counters leaving the geist eligible for undying again.
If the -1/-1 counter would reduce the strangleroot geist to toughness 0 by adding in night of souls' betrayal. Then the geist would be sent to the graveyard and the game would see that it still had both counters on it when it was last on the battlefield so undying would not trigger.

C.R. 121.3. If a permanent has both a +1/+1 counter and a -1/-1 counter on it, N +1/+1 and N -1/-1 counters are removed from it as a state-based action, where N is the smaller of the number of +1/+1 and -1/-1 counters on it. See rule 704.
