Golem Press + Vara's Sanctum are the combo you want; Bartholo may seem a bit gratuitous but he's in here as an Aegis Unblockable more than anything else.
Note that Xenan Temple + Pristine Light combo means you can wipe your opponent's largest units and draw them into your own hand. Use this constantly because your list is exceedingly unit-light.
Market is still a bit in flux.
Golem Press and Vara's Sanctum are set in stone as extra copies of your two big combo pieces. The rest are tailored as follows:
Avigraft / Bloodlust - Counters big time / FTP
Vara, Vengeance-Seeker - Counters Hooru / Stand Together
End of the Story - Counters "decks which have units"
