Boss Sentinel Role Card

Trigger - Enter: Attach this to the Boss. Then, for each opposing player, put a Doubt on their Clash card with the highest defense power.

Attached card gets +0/+2 and, "Counter - Attack: If the attacking Clash card has no Doubt, it loses all abilities until end of turn".

While there are two or more Minions in play, the Boss can't be attacked.

The cost of all Clashgrounds is increased by one.
