Taruda, Master Calibrator

When Taruda enters the battlefield, search your library for a Trap card, reveal it, and put it into
your hand. Then shuffle your library.
Trap cards in your hand have quick-trigger (If
an opponent attacked you with a creature or targeted
you or a permanent you control with a spell this turn,
you may pay {1} and spend only mana of this spell's
color rather than pay this spell's mana cost.)
