To counter the earth wall of 10000 miles I would simple either attack over the walls with an attack that could either be fired as a motor type to go over the top of the wall such as (Katon: Gōkakyū Hitoame no Jutsu)Fire Release: Great Fireball Shower, or I would use a large attack to break through all of them such as (Raiton: Gian) - Lightning Style: False Darkness, but I would prefer to be more subtle as it is my style.
To counter the last one I would either merge with something around me, the ground etc using the (Hiru Banshō: Bōka no Jutsu) - Leech All Creation: Attack Prevention Technique or go up into the air to gain the advantage over my opponent in the process using the mandalore jetpack.(didn't post this one as the technique is lots of writing to get to it)
