<p>with one of the main mechanics of Amonkhet being -1/-1 counters, i am worried about how that will affect my +1/+1 counter deck, specifically <a class="mtg-autocard" target="_blank" rel="noreferrer" href="http://gatherer.wizards.com/Pages/Search/Default.aspx?name=%2b%5bGleam%20of%20Authority%5d">Gleam of Authority</a>. if a +1/+1 counter cancels out a -1/-1 counter, will it go away if a creature has both, rendering my creature with <a class="mtg-autocard" target="_blank" rel="noreferrer" href="http://gatherer.wizards.com/Pages/Search/Default.aspx?name=%2b%5bGleam%20of%20Authority%5d">Gleam of Authority</a> less powerful?</p>

# Do +1/+1 counters go away with -1/-1 counters?

(Asked by: username_0 on 2017-05-25)

with one of the main mechanics of Amonkhet being -1/-1 counters, i am worried about how that will affect my +1/+1 counter deck, specifically [Gleam of Authority](http://gatherer.wizards.com/Pages/Search/Default.aspx?name=%2b%5bGleam%20of%20Authority%5d). if a +1/+1 counter cancels out a -1/-1 counter, will it go away if a creature has both, rendering my creature with [Gleam of Authority](http://gatherer.wizards.com/Pages/Search/Default.aspx?name=%2b%5bGleam%20of%20Authority%5d) less powerful?
