Candles' Glow

Damage prevention with a lifegain rider has historically lived at common and rarely earned a slot in a competitive deck. The splice cost is what changes the math here. For two mana, the prevention-and-gain clause grafts onto any Arcane spell as it heads to the stack, so a defensive effect that would otherwise demand its own slot rides along for free. The Arcane-and-Splice engine was built around exactly this exchange: each spliced clause is a card you reveal and pay for rather than cast outright, letting a single Arcane spell carry the stacked effects of three or four others. This one occupies the defensive seat in that engine: the buffer that absorbs three damage aimed at your face, or the cushion that keeps your attacker alive through a block, all paid for without committing another card to the stack. Read in isolation, the text looks like a small heal with a minor life bump tacked on. Played as designed, it is a prevention shield you hold in hand and bolt onto whatever Arcane spell the turn happens to call for: never quite a card you cast, never quite a dead one either.
