Wouldn’t it be cool if there was a card that said at the start of the game:
… all cost of cards cannot be changed.
… all quests are dropped.
… can only gain one mana per turn.
… all players cannot make copies of any kind from any source.
… all hero powers can only be used once a turn, no matter what.
etc.
Wouldn’t that be fun?
3 and 5 would be geared towards wild as standard doesn’t have enough means to make those to happen frequently
“start of game: make a specific deck archetype insta-lose” will never be fun
Ranked isn’t about having fun though, unless you don’t care about advancing.
as long as the mana cost of the user of those cards increases by 3
Hmm, lets see…
Start of game, all “discover” effects become “random card” effects.
Start of game, cards that would be cast when drawn are instead drawn normally.
Start of game, if a player would draw cards through a card effect, that player draws that many cards minus one (1).
Start of game, hero powers cost four (4).
Just off the top of my head.
