If I steal a monster with Mark of the Rose or Falling Down and it is flipped face-down, do I keep control like with Snatch Steal?!
A monster is taken by an equip and then flipped face-down.
Yes. The equip is destroyed, but control remains with the player who took it, similar to the Snatch Steal interaction.
If Prisma sends Summoned Skull, does it count as an Archfiend for Falling Down?!
Elemental HERO Prisma sends Summoned Skull to the GY to copy its name.
Yes. Summoned Skull is treated as an Archfiend, so it counts as an Archfiend for Falling Down.
