Wall of Protection can be very annoying when facing the promo Goliath, because he pushes back your here, negates banding, and cannot be negated. You can present another hero if you would like, but you are protected from that last part with wall of protection, so unless you have a giant slayer -who isn't pushed back- or discard him/convert him/are protected from him, if you face a goliath in a tournament, you will get destroyed. Good deck!
God Bless!
