Then damage output is dropped and Blitz wouldn't come as early as one would like.
If things are working properly, and you're under SoP for most of the early game, damselflies get out to receive SoP buffs earlier than the golem/seraphs would, so (usually) would wind up with similar damage apiece when you pop the SoP, but there'd be more of them, they'd fuel additional SoFrs, and they'd be available as first-turn cremate targets in situations where you didn't topdeck two of your four towers/pends.
Blitz is probably nearly useless against 100 hp opponents, though, so yeah.
