Bulwark Guardian

At the start of the Boss Turn, put one Boss Counter on this. Then each player chooses a ready Clash card they control and it can't obstruct this turn. If they don't, they add a Doubt to a Clash card they control.

Whenever an opposing Clash card obstructs, put one Doubt on that card.

When the players advance, flip this.

Skull: Minions get, "Counter - Attack: If this is defending, deal X damage to each attacking Clash card where X is the number of Boss Counters on the Guardian".
