Still enjoyable, but still a bit too easy: I don't think I've ever lost a game, and after the first couple of battles my deck is regularly winning on the first hand, often in the first round.
I think you can afford to be more punishing with enemy effects, and much less generous with stickered cards, shops, cost of sacrifices, duplicate etc.
This strategy is pretty straightforward to execute:
- Start out picking extra slots (having one more ally is usually very impactful)
- Spend money like 40% on building a strategy which massively overpowers one card, and 60% on sacrificing all cards which don't contribute to that strategy (Gnomes, then usually farmer, then scouts)
- Skip unless you're offered a card which significantly contributes to your strategy
- Get the deck down to 5-7 cards and play the same winning hand every battle
