And why would anyone use a shield like that? Same mechanic for 1 turn. No one will use a shield that only has DR for 1 turn at a time. The point of this shield is to use their creatures against them. If they don't have fire quanta, then they can't rebirth the phoenixes. Also, people spamming phoenixes does not help this shield in any way. Now, if people spam phoenixes and they get killed, it helps this shield. But if the have phoenixes, they have the fire quanta to use rebirth and reduce the DR of the shield.
