This is a fun little Potion board.
All of the Potion cards are decent+: Start with an Apothecary, grab Alchemists and Golems later and of course you should get at least 1 Witch.
Monument should be a handy dandy card here to make up for the lack of VPs.
Maybe even grab 2 Potions, but maybe not; you can draw them with Apo and have only 1 buy.
The lack of a +Buy is really hurtful and in favor of the Witch-BM player, but I think you should be able to overcome him with Golems and multiple Monuments.
