This is an excellent monster to use in a "Crystal Beast" Deck. You can Special Summon the materials needed to Summon this monster with "Crystal Beacon" or "Crystal Abundance". (Note: When using "Crystal Beacon", make sure to Summon "Crystal Beast Ruby Carbuncle" to swarm the field with Xyz fodder. If you have another Level 3 monster, you can overlay "Ruby" with it to Summon "Number 20: Giga-Brilliant" to boost the ATK of "Shock Master", making it an even more formidable foe.) "Shock Master" is especially devastating after using "Crystal Abundance", as your opponent will find it difficult to top deck their way back into their game after having their field cleared.
Xyz Summon this monster through this procedure: First Normal Summon "Rescue Rabbit" and use its effect to Special Summon two Level 4 Normal Monsters. Then use "Double Summon" to Normal Summon another Level 4 Monster Card to the field. Then overlay the three monsters to Xyz Summon "Shock Master".
Use "Ultimate Offering" to Normal Summon all 9 of the "Gadget" monsters to Summon 3 copies of "Shock Master". Use each of their effects to make Monsters/Spells/Traps useless and OTK the opponent.
A much more practical option this format, where Continuous Trap Cards won't last a turn is to use "Gadget" monsters with "Chain Summoning" and any chainable effect ("Book of Moon", "Enemy Controller", "Crashbug Road", "Kagetokage"). Summon the "Gadget", then chain the chainable card to the "Gadget" addition, then chain "Chain Summoning" to that. Afterwards, Summon this card. This has the advantage of protecting "Ultimate Offering", and also allows for the play to begin on the first turn.
This card can be used with "Royal Decree" to further limit the opponent.
Use this card with "Destiny HERO - Diamond Dude" to circumvent bypass the restriction on activating Spell Cards, as the effect of "Diamond Dude" does not count as the activation of a Spell.
Combine this card with "Naturia Bamboo Shoot" and "Solemn Warning" to prevent your opponent from playing any cards at all. Your opponent will be unable to play any Spells or Traps, use any monster effects, or Summon a monster thus creating a complete Lockdown, however, note that this card's effect will disallow your own use of traps on your opponent's turn as well if Traps are selected as part of it's activation.
Another lockdown is also possible with the combination of this card (blocking Spell Cards), "Royal Decree" (blocking Trap Cards), and "Vylon Omega" (negating monster effects). Only usable for 3 turns, though.
