Plasmarrow, Flaming Coals, etc. Ability Lengths

Do the effects of those attacks (Plasmarrow, Flaming Coals, Ice Disks, and Whirling Wail) last until the end of the turn or just for that burst phase (if one plays out) since it doesn't say specifically when the effect ends.

TLDR: End of Turn

6.4.1. The last step in a player’s turn is the Recovery Step. During the Recovery Step, the following events occur simultaneously:
1.) All damage is removed from Creatures in play.
2.) All effects that last "until end of turn" end. Any effects which are not tracked by an innate ability or counter and don’t have a specified duration also end now. All such effects end simultaneously and cannot result in a Creature being destroyed.

Thats what I was thinking too but the tradecardsonline say apply this only as this card resolves and Slim25 and I were playing and brought up the point that if this is until end of turn, shouldn't Enre-hep HM ability also be till end of turn and not just in a burst?

With Enre-hep, you play a Mugic, and then copy that mugic while its on the burst using Enre-hep. When Enre-hep resolves, he creates a copy of the mugic and reopens the burst. Then the copied mugic effect ends when the copied mugic would end (usually end of turn), and copies cease to exist when they leave the burst because they aren't a card. But the effect still lasts as long as the Mugic would.

Is this what you were asking?

I was more concerned with what is correct, the rule saying any abilities last until the end of turn unless stated or if tradecardsonline is right saying it on;ly applies in the burst?

Rules last until end of turn unless otherwise stated. Rip TCO...
