Shield Spell/Trap Cards

Shield is a new kind of spell/trap cards. Their symbol is a shield, as its name indicates. When these cards are actived, they create a shield that protects a card (monster/spell or trap) or even the player's life points. Sometimes they target a card to add a new effect whenever the target card's effect is activated. After they active, they dissapear from the field and goes to the graveyard, but the effect of the shield is still active unless the card says the contrary. The player can only have 5 shields active at the same time. They have the advantage that they cannont be destroyed as they leave the field but their effect remains. Nevertheless, there is a special effect of some monsters or spell/trap canrds that can destroy the shields.

For instance:

Field Barrier:
