Regarding keeping Serum Powder in with the transformation, @vaughnbros, I think with your list (at least the last XL dredge list you published) it makes less sense to keep in. @ajfirecracker's sideboard is entirely focused on the Depths plan (not to say the deck is post-board, but the SB is), so Powdering into that is a realistic option. Your sideboard, on the other hand, is less focused on drawing the Depths plan in the opener - and given that each piece is only a 2-of, with no hexmages, Powder is less likely to give you what you need. Plus, your keepable hands have a wider variety (if possibly not quantity) of cards - for example, in the match against LSV, double Force + Stripe Mine was a fine hand that doesn't have an equivalent in the purely transformational deck. Thus, removing cards that have positive utility to keep in cards that are only useful in the opener is a less sensible choice in XL.
