Archifiend roar: Pay 500 lp and destroy it on the end phase hmmm
Call of the archifiend: Send 1 fiend monster from your hand hmmmm
Both are traps so you have to SURVIVE a turn to use them...
Monster reborn reborn is a spell and have no cost...
Monster reborn2 banish the rest of non-selected monster, which makes it harder to use after each usage. Also it is almost get archfiend emperor with this unless you have 3 of them in your grave. Don't forget the fact that your opponent choose the special summoned monster for you, so no way they are going to choose archfiend emperor.
Escape from dark dimension is a box UR, not everyone can afford them on top of archfiend deck, a naturally expensive deck due to emperor also being a box UR. If you have it, then go ahead and combo it with this card but no way I'm going to spend for a box UR just for a tier 2 deck.
