Noone else could give any feedback? Or just ideas to bounce off?
The first idea isn't too bad, but it also means novas, rustlers, really any alternate methods of quanta generation, not just the less used damselflies and gnome gemfinders.
It seems much easier for more upgraded players. I assume it is more directed to experienced players, looking to test their deckbuilding. However, the random pillars could be a problem.
If you are just looking for creative deckbuilding, they could tell you your pillar types, and how many, and you could build a deck around what is given.
The second idea I am worried about. If you are paired up with a completely random player, that is a problem. Two decks don't necessarily work together. In fact, some could work against each other (an afla + Bonds deck with an unupped pandemonium deck).
However if this was developed so you could know your partner, and therefore plan decks and strategies, and play a very powerful FG (Much harder than the current ones, to balance the two players). There are some interesting possibilities there, since both players can go duo/trio, have reliable quanta sources, and have the scope of a rainbow together. So personally, I prefer it with a known partner, or an idea of their deck (Just a custom title such as Shrieker Rush, Adrenalined Staves ect)
