About the merchant limited format.
I agree with MarcinS it is necessary to add this constraints, is always possible to abuse of the system just by demand or being clever about which league may be upcoming at a very good time. Nevertheless, I do also agree with Nitsuj about the HUGE handicap against the new players.
I propose the following: (before saying no please read)
Trading available: this will definitively help newbies (in the site) to form a collection, is clear i would prefer to trade 1 of my
aragorn's bow than sell it and when trying to buy an
armory see that i need to sell another one. And for them i am sure it will depend on their meta game.
how to avoid "dirty strategies" to get a bigger collection with many accounts?: Weekly payment will be as 50D (diamonds i dont know to mention a currency); Diamonds will only work to pay for tournament entrances. G - Gold and s- Silver will continue to work as usual for card transactions but there will be no weekly payment, the ONLY way to earn gold is gonna be through tournaments (and not by winning games, but by position)
Prizes for collectors tournaments may be better to encourage participation.
Explanation of why it works:
1. Newbies may try for first, non-collector tournaments. Earn money and by trading rapidly build a decent deck.
2. Since you wont earn gold periodically by doing "nothing", the only way to cheat now is to make 10 accounts and participate in tournaments but this is quite exhausting and actually can already be done in the present configuration.
3. Better prizes (for collectors) do not represent an advantage over new players, why? because only the first 3 places (under a low mutiplier proportion maybe) are gonna get them, the thing: make it really hard to win this prizes as in real torunaments.
Well, I have no clue how hard is it to program trading, but for sure should not be a problem now paying attention to trades cause they are no profitable. Hope my idea is not stupid.
