I agree with DD - the event card shouldn't effect our deckbuilding. If we get a few extra cards, that's nice, but it's not worth losing a match because we tried to get bonus points and messed up.
Some guesses on the other team's decks:

expect lots of healing, I'm guessing theirs will be more on the stall side than the rush side

probably going to involve archangels and possibly crusaders

with eternity they can stall indefinitely and dune scorps are great for wearing out opponents over time. If there's one element that has the capacity to stall, it's time - unless we have reason to believe they're going to rush to try to throw us off.

very high probability of permanent control, other than that I'm not sure

5 out of 6 of their winning decks last round had discord - it's proving to be very popular. I'm betting they're going for a rush, possibly with novas.

no predictions for earth, I'm not sure what they're going to do

might go for a rush involving momentum, or one with graboids

I'm guessing they'll go for a cremation rush, considering it's the only thing that worked for them last round, though a stall is possible
