Keyword notes

Sharpen - Put a +1{p} counter on the object. Remove all +1{p} counters from that object at the end of turn.

Sharpen is a new effect keyword available on some cards in Compendium of Rathe.
Sharpen is a discrete effect and a delayed-triggered effect. When you are instructed to sharpen, you will put a +1 counter on the targeted object or object specified after the sharpen keyword. At the end of the same turn you sharpened that object, sharpen’s delayed triggered effect triggers. You will remove all +1 counters on the sharpened object when that triggered effect resolves
When resolving Sharpen’s triggered effect, you will remove not only the +1 counter put on the object by the Sharpen effect, but all other +1 counters on the object are removed as well. All other counters remain on that object.
Non-sharpen effects that put +1 on an object do not count for the purposes of determining if an object was sharpened.
Resolving a sharpened effect on an object results in that object having been sharpened for the purposes of cards and effects.
When resolving a sharpen effect, if you are unable to put a +1 counter on the object, it will still count as having been sharpened. (This is similar to intimidating an opponent with an empty hand).
An object can have +1 counters and -1 counters at the same time. Adding +1 counters to an object that already has -1 counters does not cancel the existing token out.
