How do Steam Vent and Esper Dash interact?
According to Sirlin (the creator of the game):

In all my games and also in MtG:
If an ability says &quot;You can do X&quot; and another ability says &quot;You can't do X,&quot; then &quot;You can't do X&quot; takes precedence.

This means that Steam Vents would prevent Setsuki from using her Esper Dash to use a dashing strike on the next turn.
