Just wanted to say I do enjoy the game but try not to "overplay" it. I do hope expansions comes to BGA and breathes fresh air into the game. I will still play it occasionally though just like many other games on BGA.
I think the most boring matches are by far the ones where a player takes Dragon Lair turn one and wins barely even using the artifacts in their deck. All the other matches are quite fun... then again there is a Dragon Lair in 50% of the matches. Luckily it is quite beatable I have had some other strategies pay off just as good or better.
Alchemist Tower I don't find as bad since it isn't as expensive and "normally" the plays are quite different while Dragon's Lair is just untap it as much as possible and play 1-2 dragons if available.
Supposedly Catacombs is super powerful too but haven't had people go for that one as much.
