Item stacking rant

Think the one case where it's not really clear how multiple items interact would be the (arguably odd...) case of a commander bearing multiple shields. I'm not sure that anybody would ever field a commander with both Aegis and Barrier, but if somebody did, I have no idea how the blocking rules would work.

The petrification and immunities will work as normal, but that's not part of the blocking rules.

For any commander with two different shields, both shields add their parry value in the stat screen (better use a horned helmet or something to avoid the useless kick). So I assume two enchanted shields add +14(-2) to defence. I wonder what protection value is added when an attacker hits the shields though.
