4F Keelo got hit pretty hard by the rotations out of expedition. The other 4 drops for the deck are not stellar, so instead the toolbox aspect is emphasized rather than going up the chain and cheating big things out.
There are no ways to cheat out
Severin of the Dark with Keelo, but it also doesn't really matter. With all these duals and Interloper triggers, you can build up big surge turns with Severin regardless, and this gives the deck a nice cushion of lifegain and inevitability.
Desert Alchemist was a nice print, both in terms of function and keywords.
Grazer is the best card in the deck, and that probably won't change. Ayan. the Abductor gives you a nice ambush threat and another lategame.
