That could be cool. In ARC the card limit now is 3, except for cities where it's 1, the deck only contains 45 cards.
But we could follow your suggestion, and have a limit by a 'rarity' indication.
Building a deck would require more thinking and pre-game tryouts.
Strategies around a single card would be possible, and you'd have to take care of that single card, being able to search and fetch, and protect it against destruction, etc ...
ARC-wise something like this could work
Common : 8
Rare : 2
Just a bit of fun using the powers of 2. Mythical could be a card that's not in the deck at all, but could be summoned by other cards out of the blue (unglued/unhinged style).
Good input, thanks,

For example, you might be able to stick four commons in, but a rare card could only be in there once. This would allow some cards to be slightly higher powered, without it completely breaking the game. Thoughts?
EDIT: There could also be a limit on how many of each type can be put into a deck. Say you have the following levels of rarity:
There could be a limit of say, 1 Legendary, 3 Rares, 10 Uncommon, and none for Common.
I can't say how this would work in practice, but it seems like it could prevent people from stuffing the most powerful cards into a deck while allowing them to exist.
