Majesty's Fiend vs Michion the Timelord

Question

Majesty's Fiend:

Cannot be Special Summoned. Monster effects cannot be activated.

Michion the Timelord:

Cannot be Special Summoned from the Deck. If you control no monsters, you can Normal Summon this card without Tributing. Cannot be destroyed by battle or card effects. You take no battle damage from attacks involving this card. At the end of the Battle Phase, if this card battled: Halve your opponent’s LP. Once per turn, during your Standby Phase: Shuffle this card into the Deck.

Q1- Can player A's Michion be normal summoned from hand without tributing if Majesty's Fiend already on player B's field?

Q2- If Michion battled Majesty's Fiend:

• Will Michion be destroyed or not?
• Will Michion's owner take battle damage?
• Will Michion's effect of halving LP apply?

Q3-: Will Michion be shuffled to the deck on standby phase (if both monsters didn't battle)?

Answer 1

Q1: Yes, Michion can be Normal Summoned from hand.

This is not an activated effect, but a condition on the card itself that grants a summoning procedure. Therefore, Majesty Fiend's effect does not prevent it.

Q2: No to all three.

Michion's effects which prevent his own destruction and prevent damage from battle are not activated effects, but continuous effects. Therefore, Majesty's Fiend does not prevent their application. The effect of halving the opponent's LP, however, is an activated effect (you can tell by the presence of the colon); it will not be activated at the end of the battle phase due to Majesty's Fiend.

Q3: No, Michion will remain on the field.

Michion's effect to shuffle itself back into the deck during the standby phase is an activated effect (again, note the colon), and therefore is prevented by Majesty's Fiend.
