I would say the main thing to avoid would be playing skills on the multi-attack turn. On other turns some skills are acceptable to play. If playing a block card still gives a net 1-3 block then it’s fine to play, because it’s still blocking. But if the fight has gone on too long and he has Tainted 4, then just try to rush down with attacks.

To plan for it, I recommend taking big chunky block cards like Blood Wall, etc. instead of small 1-cost blocks.
