Interesting (sorry I say that word a lot) "As a cost for a Spell or Trap card" needs to be more specific: Change to "When this card is sent to the graveyard as a cost..." if that's what you mean

It should discard itself as the cost for the searching effect.

This one is alright too.

As individual cards they are OK, but you have 9 cards in your deck that negate the cost of a spell/trap, and the deck as a whole I'm worried about.
