Dimension Fortress Weapon: If a card needs to be sent from the Deck to the Graveyard because of a card combination that renders the usual resolution impossible, that card is still sent to the Graveyard even if “Dimension Fortress Weapon” is on the field.
Example #1: If “Dimension Fortress Weapon” is on the field and you activate “Conscription”, and pick up a monster that could be Normal Summoned, but your Monster Card Zones are full, the monster is sent to the Graveyard.
Example #2: The same is true for extra monsters from “Enchanting Fitting Room” that cannot be Summoned due to lack of available Monster Card Zones.
Example #3: “Crystal Seer” is flipped face-up while “Thunder King Rai-Oh” is on the field.

Machina Fortress: You can negate this Summon with “Thunder King Rai-Oh” or “Solemn Judgment.”

Morphtronic Forcefield: You cannot activate “Morphtronic Forcefield” if “Thunder King Rai-Oh” is on the field. If an effect is chained to “Morphtronic Forcefield” that Summons “Thunder King Rai-Oh”, you will not be able to add a “Morphtronic” monster to your hand, but “Morphtronic Forcefield” will still negate the Spell or Trap Card that it was chained to.

Power Tool Dragon: You cannot activate “Power Tool Dragon’s” effect while “Thunder King Rai-Oh” is active. If you activate the effect, and an effect is chained which places “Thunder King Rai-Oh” on the field, proceed with “Power Tool Dragon’s” effect but the 1 picked card goes to the Graveyard instead of your hand.
