Ok, Rav and I (mostly Rav) did the conversions.
Our vault consists of the following cards now:
Rav's deck next round:

And our spare cards. They should work quite well to adapt to anything the opponent throws at us. I didn't get the pendulums yet, we can convert non-needed cards to that when we know who we are fighting, and if Rav wins, we have even more options next round (using the tridents for example).
