Rulings:

• 5/3/2019 The War of the Spark set doesn’t include any ways for players to have counters, but some cards in other sets say that a player “gets” a counter of a certain kind. Notably, emblems aren’t counters.
• 5/3/2019 You can choose any permanent that has a counter, including ones controlled by opponents. You can’t choose cards in any zone other than the battlefield, even if they have counters on them.
• 5/3/2019 You don’t have to choose every permanent or player that has a counter, only the ones you want to add another counter to. Since “any number” includes zero, you don’t have to choose any permanents at all, and you don’t have to choose any players at all.
• 5/3/2019 Players can respond to the spell or ability whose effect includes proliferating. Once that spell or ability starts to resolve, however, and its controller chooses which permanents and players will get new counters, it’s too late for anyone to respond.
• 5/3/2019 If a spell or ability puts counters on a player or permanent and then instructs you to proliferate, choosing that player or permanent will give that player or permanent another of those counters.
• 5/3/2019 Putting loyalty counters on planeswalkers doesn’t cause their loyalty abilities to be activated.
• 5/3/2019 Some spells that proliferate may require targets. If each target chosen is an illegal target as that spell tries to resolve, it doesn’t resolve. You won’t proliferate.
