Let's see, for team
what went wrong.
The first thing that comes to mind is our initial vault. We had two options to start our vault with, 64 pillars or 90 (this is on top of the 22 pendulums), we went with 64. It was basically just two of us talking about it (dema and myself) and it probably ended up being the biggest factor for us. We actually needed to convert just to make the initial set of 9 decks for the first round to give you an idea of how tight it was. Now consider that team earth fielded some stall decks which were as big as 40 cards and mostly pillars. That took some effort. A lot of deckbuilding consisted of telling people they had to take their deck and make it work with 2 less pillars or something like that.
So yeah, our initial pillar load required a very high winning ratio to be viable which we simply didn't deliver.
That became a constant thorn in our side, making us cut corners on decks as well as salvage/discards. Converting max every round just held us even in the same predicament we started in. It also affected deck choices sometimes, as we simply couldn't field too many of the big stalls. In round 3? or maybe 4, we had to discard some creatures we needed to keep in order to keep the pillars viable. That lead to a shortage in creatures we had to fix in later rounds through salvaging (like our gravity deck was built out of salvaged chargers specifically to fix that problem that round - no pillars for stalls, no creatures for damage, that deck was the best we could put together purely out of salvage, it was that or something with no damage output at all).
I believe it was round 4, we cut corners on a bunch of decks trying not to suicide, and lost far too many of them. That crushed our vault leading to the multi-suicides in the next round. That once again was a pillar limitation, there was no way we could field 9 viable decks with the pillars we had remaining after the previous huge losses. In round 5 we could either cut corners again, or condense into properly supported decks and take the giant hit. After failing so badly cutting corners and trying to stretch decks in round 4, we condensed in round 5. That was made worse by not being able to field stall decks and having to discard them when we landed with 272 cards and having to field 270 of them in the 9 decks.
The only other thing really was some general activity issues. The members were all great - it was a good collection of players - but I found it hard to get people to test decks (there were some standouts like timer who were always involved with their deck testing). Testing was further complicated by a few of our members not having all the rares or upped cards to build the decks we needed to test against too - that exacerbated the activity/testing issues a bit. In the best rounds maybe half the decks would ever get tested, in the worst rounds, maybe 1 or 2 would. That made a difference too. You can kinda see activity levels from the posting in the earth section even though we had a separate chat. Timer was a lot more active than it looks from posts, but the rest is fairly accurate proportion wise.
Anyway, that's about it from my perspective. Good luck to those that remain in war.
