Shine Striker and Shine Slasher

[Thomas★Zero 19]

So Shine Striker and Shine Slasher are LIGHT Fairy Pendulum monsters that have basic but powerful abilities where their Pendulum effects scaling 0 to 8 allow you to increase your monsters ATK and DEF while also decreasing your opponents where the cards place would also be able to return to the hand. In addition to this they can also discard themselves to destroy a Monster or Spell/Traps making them viable hand traps.

In any deck these cards can be handy both as support and disruption that enables you to pendulum summon if you have both on the field.

Making them viable hand-traps? More like broken hand-traps. Slasher is pretty much a better MST as it can be used even when going second, and benefits from extra support as a monster (e.g. searchable by Sangan, Benten, etc.).
Striker is more potent, being able to also pop monsters when going second, and it some instances it can do so before the monster uses any Trigger effect, effectively working as a better Effect Veiler.
At this point the Pendulum Effects and scales are the extra features, not the other way around, and they only make them even better.
