Oftentimes, an early Mummy will have 0 Power. To my understanding, if Mummy attacks with 0 Power his Drain 2 will not trigger even if the Dungeon wins Combat.
Correct, Drain will not trigger.
Over time I adapted to playing against Skwee and realized that he is not as impossible to kill as I initially thought. I had also forgotten how good Greenknee is. They are much closer in power than I originally believe and I am quite happy to have both in my Dungeon as it makes for a better game all around.
This is really good to hear.
Adult Onyx Dragon Many of the support cards help to get him into play with additional Characters -- Mastermind, Rapid Developments, Lost Cave. Those cards tend to produce wicked Encounters that demand you have Run Away (or at least Delay Inevitable) in your deck.
Don't forget Murky Swamp with the Onyx Dragon.
Time Wasted Because it can't be flipped, I have rarely been able to play this card.
It's dangerous near the end of the game as it begins to grind down your deck when it comes in to play. At 4pts, there's not going to be much to encounter, and at the end of the Turn you'll have to discard down to your Hand Limit. Playing Champion/Master as needed is a decent counter to this, nice catch.
Falling Stones I am less convinced of, but it is another one that I think demands to be tried before passing judgment.
Try this with Labyrinth. 3 Power coming at all 4 Adventurers can be brutal if you don't have the right defensive cards for the cost of 1.
