Problem with that is that i don't think you can automatically tell if a team will necessarily suicide or not. Earth didn't have to suicide 4 times but they CHOSE to this round. They also chose to suicide against teams they probably thought they had the lowest win percentage against. Also due to suicides being viable by all teams earth could have made a legal suicide deck (with no pillars) in the hopes of the other team making an illegal/suicide deck.
This would also slow down the whole process in making pairings.
I don't think teams suicide depending on whether they "like" a certain team or not. The choose it depending on whether or not they have a better chance of winning vs certain teams. No way do i believe that Xinef and Terro chose to suicide against team Death due to popularity.
For this round Earth just chose to suicide against the #3 team and the #2 team. Nothing really seems shady about that.
This conversation would be easier post war, when details can be known. Suffice to say, the choices of suicides were tactical in nature, and designed to leave earth with the strongest chance of wins, both in round 5, and, just as important, with viable decks for round 6.
Yes, earth had 144 earth cards for round 5, we could've fielded 9 legal decks if we were forced to, but nearly all would've been destroyed in combat by being too thinned out. Even worse, by fielding 9 weak legal decks in round 5, we would've been forced into a repeat suicide scenario in round 6 as well, as whatever we scraped out of round 5 with would've still been weak, and the options to strengthen them would now be gone. As it is, hopefully round 5 will be the last we deal with this suicide nonsense, regardless of win or lose.
Let's put it this way, we viewed forfeiting 120 cards out of 272 as the preferrable option to being forced to field what we would've had to do to make 9 legal decks and I feel relatively good about the choice. I still think it would've sealed our fate in round 6 as well, even if we'd won the same amount (since the surviving decks would all be weak).
The 30 card brackets also struck earth particularly hard. As you can see from our suicide salvages we've been handing out, we had a lot of stall decks. Stalls were half of our remaining deck concepts. Off the top of my head, we had a functional antimatter stall, a thorn carapace stall, a miracle/morningstar stall, a trident/water stall, a straight earth stall, and a poison stall. All but one of which needed to be pitched out in suicides because most don't really work that well in 30 cards and we had to field our entire vault one way or another. You can see pieces of these all over the salvage.
Bad planning? Half of this was salvage pickups. Walking in, earth needed stall decks as options and some of these were quite good. Is it our fault that these things vaporize as viable options when we find ourselves with 272 cards - the same moment we are required to field the entire vault in formats of 8x30 decks and 1x32? Even if it is poor planning, if you're going to have a shot at doing well, you can't just discard your strong suits to 'prepare for down the road'. Regardless, we had a lot of better conversion candidates from unusable salvages so there were few ways to get rid of them. Take a look for yourself, awesome salvage right? That was the worst stuff anywhere in our vault - all of it. The cobweb junk.
Our vault building isn't blameless, but the 30 card brackets really drove spikes into the coffin. As soon as we touch the 270 limit earth largely loses its stall decks, which is one of earth's supposed strong points. Not to go into it too much, but the inability to field stall decks had a lot to do with choosing death to give salvage too. Simply put, we were better prepared to fight elsewhere with 30 cards, it was not really an option to fight death in three 30 card battles and win. Using all the key cards to even attempt that would've sabotaged most of the other matchups we had. It takes a lot of stuff to break down wings and bonewall combos, esp when they know you have to. It's much easier to field a stall against decks like that and not try to drive through the opponent's strengths, but that was removed as an option for us by the tight brackets, while simultaneously making us discard all our stall decks.
Sometimes you lose more by fighting the wrong battles.
Fire was a larger possibility for a fight. If we were able to field another deck it would've been there. But we weren't able, so it never came to that.
