If "Psychic Shockwave" is Chain to an opponent's Trap Card, there the benefit of negating that Trap Card when this card is Summoned (so long as it is not a Counter Trap Card).
Use "Jinzo - Returner" to return this card to the field after it has been destroyed. Since "Jinzo" won't last past your next End Phase if revived this way, replace it with "Jinzo - Lord".
"Dark Grepher" can be used to send a "Jinzo - Returner" from the Deck to the Graveyard. The cost of the effect of "Dark Grepher" or its inherent Summoning procedure can also be used to easily send a copy of "Jinzo", from your hand to the Graveyard. "Jinzo" can then be revived by the effect of "Returner".
In a scenario where your opponent plays "Skill Drain", normally, if that card is already active, "Jinzo" will not be able to negate it. Use a "Forbidden Lance" to fix this permanently.
One can Pendulum Summon this card in inclusion to other monsters, so that one will prevent any possible responses to said Summon except for cards like "Solemn Warning".
