Nice. Better than my "Chance attacking creature gets mutated" idea
calling miss blocking for consistancy
Unupped:
solar buckler: block 1
Hope: typically does nothing
Thorn carapace: 75% poison for 1
Fire shield: deal 1
Grav shield: block if hp>5
bone shield: block 1
Bone wall: block
Phase shield: block
fog shield: 40% block all damage
Procrasination: time bubble.
Dusk mantle: 50% block all damage
reflective shield: nothing.
Jade shield: block 1
Dissipation: block all if quanta (this is in entropy deck, most likely)
Ice shield: block 1 and freeze
Analysis: 4 block for 1, 2 1/2 block all. 4 don't block any damage. 2 miss shields. 4 affect creature.
Hope is almost useless, unless it is in a mutation deck with RoLs.
I'm too lazy to see if that is balanced.
