Due to the relatively low ATK of most "X-Saber" monsters, this card can be helpful in getting the most out of using an "X-Saber" Deck.
While having "XX-Saber Faultroll" and "XX-Saber Fulhelmknight" on the field, you can Tribute "Fulhelmknight", then bring it back with "Faultroll", essentially Summoning "Commander Gottoms, Swordmaster" with no cost. This is quite a good Summoning technique, if you have already negated an attack with "Fulhelmknight" because you regain its effect and it can negate one more attack.
This card would be ideal to Summon with "Soul Exchange", you would get rid of one of your opponent's monsters and give a power boost to your "X-Saber" monsters at the same time.
Use "Mist Body" to ensure that "Gottoms" remains on the field to continue to give your monsters a boost.
