Dovin says, "Until your next turn, prevent all damage...". My opponent applied this effect to my Voja commander. Voja says, "When this creature attacks...put a number of +1+1 counters on each creature", but the Dovin effect seems to prevent Voja putting counters on other creatures, which to my mind has nothing to do with Voja's ability to do damage. All my other attacking creatures should have gotten counters and dealt damage. They didn't.
