SUGGESTION - ARENA REPLACEMENT FOR LADDER SYSTEMLadder system:
The Ladder consists on 21 Tiers (0 to 20) with 21 steps on each Tier (from -10 to 10).
1. How to submit a deck to the Ladder
As Fippe said, people will have 3-4 decks. Let's call them 'deck X' (as they are called deck 1, 2, 3, etc.). In the editor, there will be 2 extra buttons: Submit to Ladder and Reset Ladder. That will submit the 'deck X' to the ladder that deck is, in step 0.
2. Which is your Tier and how does it work?
Each submitted deck of each player is in a Tier, independant from the Tier the player is.
Each deck the players have start at Tier 0 step 0, same as the player.
When a player enters to the Ladder, he plays against a random deck on the Tier the player is.
If the player wins, the player goes a step up and the deck he defeated goes a step down. If the Ladder deck defeats the player, the player goes a step down and the Ladder deck goes a step up.
When a Ladder deck is in step 10 and wins against a player, it goes to the next Tier on step 0. If a Ladder deck loses and is on step -10, it goes down a Tier in step 0.
Being on step -10 of Tier 0 and losing leaves the deck out of the Ladder. Being on Tier 20 step 10 and winning wins a damn hard achievement.
Same does the player: Win in step 10 --> Go to next Tier on step 0. Lose on step -10: Go down a Tier on step 0.
Making a Ladder deck reach Tier 20 will be hard, same as reaching Tier 20 it for the players.
Each Tier can optionally have a name, to make it more friendly. In BattleCry they are called Wooden Challenger, Wooden Contender, Wooden Veteran, Steel Challenger, Steel Contender, Steel Veteran (and continues with Copper, Silver, Gold, Platinum)
3. Rewards
Each time a deck defeats a player, the deck's owner gets some cash. The players get the same cash no matter which Tier the deck is.
4. Why is this better than the current Arena?
Because of the meta. There are 21 Tiers and if a meta dominates a Tier the players will make counters, making the unoriginal deck go down. The system will tend to have a predominated meta per Tier.
5. Banners (implemented with the Ladder system, for further implementation because it needs some art)
This is something that makes BattleCry much more addictive for new players and some vets too.
Banners consist in 3 parts: Background, main and second figure.
When players battle each other in PvP, they see the other player's banner (that's the cool thing).
When an account is created, the backgrounds are all unlocked and the player starts with only 1 main and second figure unlocked and automatically selected. Backgrounds and figures are unlocked progressively with quests and achievements. Putting a deck in Tier 1 unlocks a main or second figure, same with Tier 2, same with Tier 3, 4, 5 [...] 20.
The players can choose to have their banner with any background and unlocked main and second figure, having thousands of combinations with "not so much" simple minimalistic art. Banner art are simple one-colored non animated gifs, so they have transparent pixels.
If someone (specially artists) wants to have a better idea of how the banner system is implemented and how good it sees in BattleCry, send me a PM and I will give you mi kong account (I have all unlocked).EDIT: Some banners so you can see how they look. The background, main (white-cream) and second (red) figures.
