Welcome to Gaia! ::

While I was using my R/W deck against my friend's R/W/G sliver deck when we argued about a card called harmonic sliver.

Harmonic Sliver
All Slivers have "When this creature comes into play, destroy target artifact or enchantment"

He says, when the Harmonic Sliver itself comes into play, it may destroy target artifact or enchantment. Is this true?

the point that it says "all slivers have"(global effect)gives it its own effect sense it is itself considered a sliver.

mustle sliver also gives himself his own +1/+1 sense he himself is considered a sliver.

when he comes into play himself, his ability does not trigger, because he is not in play for the stack to take effect. any other sliver that comes afterwards WILL trigger that ability

emphasis, mine.

where are you people basing your answers off? not only is it spelled out in the FAQ, but in the comp rules it's stated that any trigger that relies on something changing zones (such as leaving play, entering play, enterig the graveyard, or anything similar) checks the game state before the trigger event. therefore, harmonic sliver grants itself its own ability when it comes into play, and then checks the trigger, because a sliver has just come into play.

this is the same reason, for example, Savra can trigger off herself.

that actually says nothing about a sliver triggering an ability it would grant itself. the FAQ is much more relevant, as per my post. entire thing can be found here if you like.

In correspondence to this subject, dont all static abilities go upon the stack the instant their cards enter play. I mean dont the cards abilities themselves enter the stack before their cards do. sorry if this is confusing.

Thanks! And the wording of rules text has been the source of many a heated battle between me and my friends. They tend to not want to follow the rules verbatim.
