Also, it does not matter if multiple mark cards are played with these abilities. THey stack upon your mark and you can only click the stack of marks then. Which means one ability as far as I am concerned since there is nothing comparable to that effect.
The nature of these cards is still confusing, though.
Does our mark just come with the ability without us needing to put it in our deck? (If so, what is the point of the upgraded card?)
If we play it, will it increase our mark by 1?
Are we assuming that they're implemented alongside marks or replace the current marks?
Does the upgraded card also increase your mark by 1 without generating an extra quantum instead of being played in the permanent spot?
Until these questions are answered, it's a bit difficult to understand the limits of card design, and making an example never does harm.
