We had this one come up at the pre-release.
My opponent plays Sonic Boom EXTRA. It's got static text which says that this attack can't be blocked by attacks which have a block zone which matches the attack zone. Now, it's also a ranged attack.
Question is, can you block using an attack which has a printed block zone of low or high, but an attack zone of mid, but is also a ranged attack which may be played as a +0 Mid Block? Can you use it as a Ranged Block (the +0 Mid Block)?
It's really going to depend on which attack you're blocking with.
