My favorite deck that I made for this tournament was definitely my immortal hyper flying weapons deck:
5bv 5bv 5c5 5c5 5c5 5c5 5c5 5c7 5c7 5c7 5l8 5l8 5l8 5l8 5l8 5lh 5lh 5lh 5lh 5lh 5oc 5oc 5oi 5oi 5oi 5oi 5oi 5oi 5pu 5pu 61o 61o 61o 621 621
It's pretty basic in that it almost plays itself. The rustlers and light cards obviously tie together, and then the Quints help to make what Druidic Staves you have flying about immortal. This actually can be an effective PvP deck in this format due to the Adrenalines. If you can adrenaline a flying staff you become much harder to kill.
At any rate, I
tried to build several decks for this tournament, and I found that my decks that seemed to work best were the ones where 3 of the elements were synergistic and the 4th was splashed for a "nice" effect, but not one that was necessary for the deck to be functional. This is, of course, discounting Immos/Novas, which obviously can count as an element in and of themselves, but I was leaving out for the purposes of this thread.
One of the difficulties in a tournament like this is to get off of what preconceptions you may have going in. When I first saw the limitations my mind immediately went to Black Hole, as I'm sure it did with many people. The problem I ran into came with the quad element requirement. Whenever I tried to work Black Hole into a deck I found myself overloading on Gravity quanta to make sure I could play them, which made the rest of the deck suffer because it immediately became too large. When I tried to counter this by bringing in Time for Precogs, Hourglasses, and Sundials, and now it suddenly became Time heavy as well. So now I had two elements and still haven't done any damage to my opponent, not a good start, so I scrapped the Black Hole idea. This is not to say that others out there couldn't do it (I'm sure many did and that at least one of them will educate me, I'm greatly looking forward to it
), only that I was unable to.
Basically, I found I was able to run one element with expensive cards, my secondary and tertiary elements with relatively cheaper cards, and the quaternary (yes, I had to look it up) being quantum support (eg. Nova/Immo) or a "nice" bonus, but not essential to deck success. Like I said, I'm sure others found ways around some of my problems, this was just the process that I wound up using.
