Judge Tips – Self-Replacement effects


Today’s Judge tip is going to tackle a subject that often times confuses me – self-replacement effects. Ok, I will admit this concept should be fairly easy but, for whatever reason I struggle with it. So, let’s explore it together.

CR: 614.15 – some replacement effects are not continuous effects. Rather, they are an effect of a resolving spell or ability that replaces part or all of that spell or ability’s own effect(s). Such effects are called self-replacement effects. The text creating a self-replacement effect is usually part of the ability whose effects being replaced, but the text can be a separate ability, particularly when proceeded by an ability word. When applying replacement effects to an event, self-replacement effects are applied before other replacement effects.

Seems simple enough, right? So let’s take a look at this with some examples.

In Shadows Over Innistrad we have the card Deny Existence.Deny Existence

Deny Existence tells us to counter a spell and then to exile said spell. The result is a modification in how countering usually works. And, as we can see from the above CR citation, this is a self-replacement effect.

What about Galvanic Blast? This spell is used a lot in Modern, mainly in Affinity decks.Glavanic blast

So does Galvanic Blast have a self-replacement effect? Yep, it sure does.

We know Galvanic Blast has a replacement effect because of the word “instead.”  We can see that the spell changes when an event becomes true – in this case Metalcraft.  “The text creating a self-replacement effect is usually part of the ability whose effects being replaced, but the text can be a separate ability, particularly when proceeded by an ability word.”

In truth, self-replacement effects aren’t too difficult. It, once again, boils down to RTFC and paying attention.
