How to beat Seraphine as Swain: the early game

You own levels 1-2: you have more base damage on Q Death's Hand and an actual engage tool in E Nevermove, while Seraphine is a pure poke-and-shield enchanter with no way to punish your step. Hit level 2 on the caster minions first, root her with E and layer Q into her — she either burns Flash or gives up a big chunk. Deny her the free Q pokes by walking up behind minions so her skillshot clips the wave, not you. She is immobile and cannot leave once the root lands, so pick the moment rather than forcing one. Stack the bolts afterwards, commit once her shield has been spent on her carry, and let the fragments cover the chip you take while you wait.
