Let's say I have Caius or Raiza in hand. Then I tribute summoned Caius/Raiza but set it face down.

Q1- If next turn I flip it face up in Attack position, does it's effect activate?

Q2- If opponent attacks my set face-down Caius/Raiza, does it's effect activate?

Q3- What if I tribute summoned Caius/Raiza (its effect activated normally), then used Book of Moon to flip it face down, then flipped it face up in Attack position again, does its effect activate again?

1 Answer 1


For their effects to activate they must be tribute summoned. In this case you (tribute)set them. Therefore, you won't be able to use their effects.

  • More specifically, OP is Tribute setting them, and then OP is flipping them face up, so yes no tribute summon per se.
