Your opponent cannot target Spellcaster-Type monsters you control with Trap Cards or effects. You can only use the following effect of "Time Pendulumgraph" once per turn. You can target 1 "Magician" Pendulum Monster Card in your Monster Zone or Pendulum Zone, and 1 card your opponent controls; destroy them. Then, if this effect did not destroy 2 cards, you can send 1 card on the field to the Graveyard.
