Keyword: Pretend

The "Pretend to X" effect will cause other spells and abilities that trigger from "X" happening to trigger, without actually causing "X" to happen.

it sounds confusing but it's really simple.

e.g.
Zulaport Cutthroat's ability triggers when a creature dies.
So casting Play Dead targeting a creature you control will cause its ability to trigger, but the creature will not actually die; nothing happens to it, it won't leave the battlefield, it won't go to the graveyard, it won't prevent any combat damage, no marked damage will be removed from it, it just causes other abilities (that would have triggered if it were to die) to trigger.
All effects and permanents on the battlefield will see it dying even though it didn't die. Of course, effects that would try to target it in the graveyard after dying will just fizzle because it never went to the graveyard at all.

We all like ETB effects, but sometimes you don't necessarily want to flicker your fully assembled voltron. Maybe it's got a bunch of auras and equipments attached to it, maybe it has lots of +1/+1 counters, or maybe you want to attack with it and use combat tricks on it.
Overwhelming Presence causes its ETB effects to trigger again without losing all the resources you'd already poured onto it.

it's pretty useless for a "pretend" effect to rely on other cards for synergy, so you should probably have something with a built-in combo effect like Accursed Librarian which deals damage when an opponent draws a card, and also includes something that can cause opponents to pretend to draw a card. (you want them to suffer for the card advantage they didn't get)

it seems like a pretty fun concept to ideate around, but ultimately the design space for this effect is somewhat restricted because it's a "do nothing" effect by itself, so you're forced to bundle it with something else on the same card.

other possible pretend effects:
"Each creature pretends to attack"
"Target creature pretends to deal 1 combat damage to target player"
"Target player pretends to lose 1 life"
"A land pretends to enter" (fake landfall)
"Each player pretends to discard X cards"
"The current turn pretends to end" (causes effects that trigger at "the next end step" to happen. should it also cause "until end of turn" effects to end?)
"You pretend to cast target spell" (copy the on-cast triggers of those eldrazi spells)
