As much as I'd love to see Team Gravity take 1st place this War, I'm going to give my realistic opinion on the rankings. But before I so that, here are my thoughts on each team.
: One example of a team with veterans that know what they're doing, but may be inactive. They've also got a good General and a fairly big vault, but most of their best cards are expensive.
Ranking: Top 4 to Mid 4
: Hindered greatly by a small vault and expensive key cards. Despite this, they have a General who's familiar with War and a lot of vets. It's also worth mentioning that the Gen has also placed in the Top 4 each War he's been in.
Ranking: Mid 4 to Bottom 4
: Most of their in-element cards are expensive, their members have a high chance of being inactive, and the team itself is on the expensive side. However, most of the team consists of former/current Generals and are experienced. Their Gen is also familiar with both War and his element.
Ranking: Top 4
: Probably going to be the team that ends up being the Jack-Of-All-Trades. Not too expensive, experienced and fairly active, slightly expensive cards, good Gen, etc.
Ranking: Mid 4
: Out of all the newbie Gens (myself included), I'm convinced Kali has the best chances of winning War, since he's the only one out of all of them who was deemed worthy to be Master of his element. However, Team Earth's main downsides are that their key cards are expensive and they only have one vet in their team.
Ranking: Top to Mid 4
: This War's is the Gen's 1st War, and the team is the 2nd most expensive out of the teams. Many of their important in-element cards are also expensive. Despite this, the team has 2 vets out of 3 members, so they're more well equipped than most teams.
Ranking: Mid 4 to Bottom 4
: I'm convinced that the Gen is all bark and no bite, seeing as this War's also his 1st. However, the team has a bunch of vets and their vault will likely be fairly big. Though another one of their weaknesses is that their cards are fairly expensive.
Ranking: Bottom 4
: My team's in a similar situation as Team Earth's, but with a significantly more expensive team (Due to my screw-up). I'm also (not exactly) prone to having bad luck. There are a couple of other obstacles we'll have to overcome, but those shouldn't be too much of a problem for us.
Ranking: Mid 4 to Bottom 4
: They won War last time, and they're entirely capable of doing it again. They have the same Gen as last time, who is now much more experienced, and the rest of the team is experienced in War. Life also has fairly cheap cards, and Team Life has a decent amount of points for it.
Ranking: Top 4
: They'll likely have the biggest vault, but this is normal for Team Light. They also have fairly cheap cards, and has 2 vets out of 3 members. However, Light is known to be an element that lacks in the War meta.
Ranking: Mid 4 to Bottom 4
: Cheap yet experienced team, only a few expensive cards, and a decent General leading them. The "newbie" of the team is known to be gifted in the PvP department, so Time should have an easier time *cough* at winning War than most.
Ranking: Top 4 to Mid 4
: While their best cards are slightly expensive and the team itself is slightly expensive, it's the cheapest 4 man team and the Gen has experience with both War and the element he's leading.
Ranking: Top 4 to Mid 4
