Roll back or ban all black mana cards. It's all anyone plays.
Every game I play, everyone is just playing black mana. The color has dominated the game. The power structure each mana color plays has been overridden to only play black mana to win. The price to play 90% of the cards is ridiculous when other mana classes have the same card effects but require more costs or are easier to counter. The game has become insufferable due not being able to have any creatures on the field due to every black mana card effect being "kill any creature you want, just for one mana". Just to balance against this, you need to roll out more hexproof and indestructible cards which Wizards clearly will not do. Another annoying point is where a 3 mana red will do some damage, a 3 mana black will just destroy a card with no other costs. How does that represent gameplay dynamics? Black mana just needs rewritten. Does anyone actually want this game to be fun or do they want it to reflect an edgy 13 year old listening to Evanescence on replay?
