- 9 February 2017Skyship Plunderer's triggered ability gives only one counter of each kind. It doesn't double the number of each kind of counter. For example, if a creature has two +1/+1 counters and a charge counter on it, it gets one +1/+1 counter and one charge counter.
- 9 February 2017To give a counter is to put a counter on a permanent or to have a player get a counter. Effects that interact with a player getting counters or counters being placed on permanents interact with Skyship Plunderer's triggered ability.
- 9 February 2017Skyship Plunderer's triggered ability can target any permanent or player, regardless of which player was dealt combat damage.
