cr:6.6.5f

If the triggered effect is triggered, but there is an effect that prevents it from triggering, the triggered-layer is not created and will not be added to the stack. However, the triggering still counts towards the limit of the effect (if any).

Example: Katsu has the text “The first time an attack action card you control hits each turn, . . . ” and Tripwire Trap has the text “Hit effects don’t trigger this chain link . . . .” If the Tripwire Trap continuous effect is active and the player that controls Katsu hits with an attack action card, the Katsu triggered effect will not produce a triggered-layer on the stack because Tripwire Trap continuous effect prevents it. The next time this turn the player that controls Katsu hits with an attack action card, the Katsu triggered effect will not produce a triggered-layer on the stack because the once-per-turn limit has already been reached.
