London Mulligan has about the same chance to find Hermit as using SP.
The main difference is SP lets you keep a 7th card, but you have to exile the first 7 (hope you didn't have an essential combo piece there).
Serum Powder Pros:
-Slightly higher chance of seeing Hermit, because you exiled 7 non-Hermit cards (70.6% on 2nd hand vs 65.4% from London mull)
-Keep 7 cards in new hand
-Improves next mulligan/SP if you have to ship that hand too
Cons:
-Risk of exiling combo pieces (can't use with DR or Thassa in hand, risky with Narc or Bridge)
-If you don't need it to find Hermit, it's a dead slot that doesn't even pitch to Mox or Unmask/Force (i.e. every time you draw it and don't need it, you effectively mulliganned -1 card)
Is that worth it overall? It might still help. It's just less of an edge than it used to be pre-London.
It only boosts the 2nd hand by about 5%, and keeping the best 6 of 7 is still enough to go off. SP would show more of a difference after multiple mulligans/SPs, because of both the cards you exile and getting to keep a bigger hand with more resources.
