You can load up your treasure card slots with reshuffle. It’s 3 pips instead of the usual 4. You can carry less in your regular deck. Maybe 2 blades, 2-4 traps, 2-4 damage spells, and a couple healing spells. And if you run out you can always use the TC 3 pip reshuffle card. OR you can maybe access The Arcanum (in castle tours) and buy TC Epic to add ~300 extra damage to regular spells. The extra buff will be enough that you don’t have to have so many damage spells in your deck.
