According to the current wording it works like this: A soul shard dies->check if any other soul shard is left on that side of the board, if not that player loses. If no soul shard is created in the first place, then technically this effect would never trigger (sorta like SoFo can exceed 45 hp if it obtains the last couple without using its ability). Btw this way the last shard would not be triggered by rewind either. It would be easy enough to change the wording though, but to me it seems pretty fair this way.
Other than that if flooding doesnt work:
Normal AoE doesnt exceed 3 dmg so it would take at least 3 turns to AoE them all (with fire buckler only 2)
However plague wont deal damage until the end of their turn so 2 upped Plagues will kill them all in 2 turns (4 in 1).
Card(s)/combos that kill a single shard in 1 turn: -freeze/shockwave, buffed otyugh/scarab, gp + creatures, warden + double buff/Sopa
each of them but the last: RT, eternity, mutation, fallen elf
Forced synergy: SoSac
More synergies: Mummy rt deck,
Diamond shield, Dim shield, Wings, sundial
SoV
Fractal
Aflatoxin (fill all of the opponents slots, the kill one, play this, kill the shard
The more you know:
-SoW reflect wont work as Seraph loses spell damage after 1 turn, even if the immortality is renewed.
-dessication can actually benefit from the additional creatures, however this is probably not worth it
- it might be that some bolts will still kill it as you only target with them once in the beginning (immortal==untargettable in this game)
Suggested changes: Tbh this card seems abit weak; if you dont specifically workaround all of its drawbacks, you probably just die and right now its around as expensive as Otks, while not killing your opponent instantly and even allowing them to kill you faster; so here are 2 radical buffs:
- Summon a shard for every 20 hp your opponent has
- That portion of life is taken as damage when the shard dies ( this is actually a berf as its now worse if your opponents board is almost full)
- Killing 1 shard should have an effect on your opponent. Pick one: silence effect, cant play spells or has their effect weakened, a random card in his hand becomes unplayable (like costs 76

now), cant use permanents (also the weapon wont attack), cannot use its monsters abilities
