Standard sentinel deck, I guess, with dragons to smooth the curve and ramp up. What's not sentinels or dragons is either an explorer (ramping) or a merchant (also ramping). Deck can occasionally be slow, and that's what torches, chars and interventions are for. Results have been solid, although I have only played about 10 runs, 9 of which I got to the gauntlet boss (won 6). Not great against the really fast bosses (double damage and charge bosses), but good against the slower ones (especially the bond one).
Eight merchants to get the
Mysterium Orb, and something else (usually
Novaquake Titan, which ends the game).
Stirring Sand is the least pulled card, but it has proved itself enough times that I don't think I'll change it. I haven't had any problems with the power base, but it's a work in progress. Let me know your opinions.
Edit. Kept testing the deck, and I am happier and happier with the results. Getting to the boss is almost guaranteed. After that, it's a coin toss (slightly in your favour though).
Edit 2: Still refining. Bought the last Tocas and swapped it for one of the wakers of the agents. Also changed a few fire sigils for it's waystone counterparts. The second change was in order to get more cards for the market, or more chump blockers (depending on the matchup). So far, changes have been good.
BTW, trying the site in the market instead of the orb. I found the orb to be a ""win more"" kind of card, but which required you to have relevant cards on your hand (which, sometimes, against all odds, doesn't happen). Site does soething similar (ramping), does not require you to have played explorers, and gets you a unit by the third turn. Still testing it. Let me know what you think about the changes.
Edit 3. Feeling like this is the last update. Changed arcanum for xenan obelisk, and it feels right. Arcanum was too conditional (I felt): you needed units in the board (that had to benefit from deadly), and you still needed to draw something big (more than just merchants and 2/3 power drops, which happened enough times that it was an issue). Obelisk allows to keep the pressure up with just the merchants, or to stall better while you wait for something more impactful to turn up.
