Rune tokens are artifact tokens that you can sacrifice to scry 1. At common, Runes are just used as tokens that allow some card filtering, but moving up in rarity, Rune tokens are given additional effects that make them more impactful.

In card text or details pages, write the mechanic's code name (playtest name) between square brackets, like "[Crittercast]", "[Bushido 1]" or "[Delay 4 {2}{R}{R}]". It will be expanded to the mechanic's name plus reminder text, such as "Suspend 4 – . (Rather than cast this spell from your hand,...)"
To expand a mechanic's name but not its reminder text, include parentheses at the end of the square brackets: "[Crittercast()]", "[Delay 9 {R}()]".
