RUNE/ODDS

4/12
How many runes of one color you're running.
First channels 2 on T1; second channels 3.
How channeling works
Your 12-card rune deck sits face-down at the start of the game. You don't see any runes until your first turn. Going first, you channel 2 on T1, then +2 each turn after. Going second, you channel 3 on T1, then +2 each turn. The table below shows cumulative probabilities by the end of each turn.
Note: these odds assume no recycling has occurred. Switch to once recycling has happened and you know your exact pile state.
