Spellweaver Helix and Panharmonicon

[rufus]

Clearly, Panharmonicon (or Strionic Resonator) can double the ETB trigger on Spellweaver Helix so that a total of four cards are exiled.

The question is, what happens when a card that shares a name with one of the exiled cards is cast. Do you only copy the other card 'in the pair' or do you copy all three other cards, or do you chose one of the other cards to copy?

Suppose for example, the exiled cards are (Faithless Looting and Chain Lightning) and (Rift Bolt and Lava Spike). If someone then casts Faithless Looting from hand, which of these exiled cards can be copied and cast?

Based on the Rulings on Strionic Resonator's gatherer, you'd get to copy which of the 4 exiled cards you wish to cast.

1. I copy the imprint ability of Spellweaver Helix with Strionic Resonator and exile 4 sorcery cards. When a player casts one of the exiled cards do I get to copy the other 3 cards or only one of the other 3 cards?

You will get to copy the other three cards.
If you copy the Helix’s enter the battlefield trigger, you’ll exile four target sorcery cards. When you cast a spell with the same name as one of the exile cards, you may copy “the other”, which in case means “all other cards exiled by the first linked ability”. So if you cast a spell that triggers the Helix’s ability, you’ll be able to cast a copy of the other three cards.
