Glyph Destruction Nodes (Yellow)

When playing Glyph Destruction Nodes, you must target up to X target heroes and/or allies, where X is the number of aura permanents you control with Sigil in their name at the time you play the card. When Glyph Destruction Nodes resolves, you will deal 3 arcane damage to each of the targeted heroes and/or allies.

If you do not control any aura permanents with Sigil in its name at the time you play Glyph Destruction Nodes, X will be 0.

If any of the targeted heroes and/or allies are no longer in the arena when Glyph Destruction Nodes resolves, you will still deal 3 arcane damage to any remaining heroes and/or allies.
