Teysa Karlov + Delney

[wraith imp]

I have the following on the field

• Teysa Karlov
• Delney, Streetwise Lookout
• Zulaport Cutthroat

And I use Viscera Seer to sacrifice Reassembling Skeleton.

At the end of this interaction, each opponents lose 8 life and I gain 8 life as a result of Zulaport Cutthroat?

[tepid stream]

1. Sacrifice the skeleton to the seer
2. Zulaport attempts to trigger.
3. Teysa and Delney both see this trigger and add an additional trigger for a total of three zulaport triggers.

There is a ruling for how multiple Teysa Karlovs would stack which is a nigh identical scenario: https://gatherer.wizards.com/pages/Card/Details.aspx?multiverseid=457356#:~:text=If you somehow control two,five times%2C and so on.

many many thanks @tepid stream

[wraith imp]

@tepid stream wait, but since Zulaport itself is 2 power or less, wouldn’t this give additional activations too?

4 total perhaps?

[nocturne chasm]

Zula is getting one extra trigger from Delney , and another one extra trigger from Teysa. Teysa's ability is not a triggered ability, this may be your confusion. Abilities that say "If X would happen, Y..." are not triggered abilities, they're "passive" (I can't remember if that's the actual word for it).

[tepid stream]

Yeah, they're called replacement effects

[nocturne chasm]

Yes thank you!

[iron oracle]

they both say "an additional time"

instead of parrellell lives and other cards that say "double"

disregard my thought about ojer, im tired and dumb

[nocturne chasm]

The issue isn't the "an additional time," it's a matter of "if" vs "whenever." The "If X would happen, it instead happens twice" is a replacement effect. The "Whenever X happens, do Y" is a triggered ability. That's the difference.

[[Parallel Lives]]

If an effect would create one or more tokens under your control, it creates twice that many of those tokens instead.

is also a replacement effect, so even if in some hellscape you cast [[Opalescence]] and then somehow reduced Parallel Lives' power by 2, its ability would not be doubled by Delney.

Each other non-Aura enchantment is a creature in addition to its other types and has base power and base toughness each equal to its mana value.

I know it's not hte argument you were making, just trying to make another example.
