What makes this an all-timer for me is that this card has two different designs in the same set, and they both suffer from the exact same problem
"It was an identity problem
At the beginning of your end step, create a 0/0 colorless Construct artifact creature token with "This creature gets +1/+1 for each artifact you control." The ability of that Construct token does count the Construct itself, so it'll be at least 1/1
This comprehensive breakdown details the exact identification markings, market values, and structural differences of these premium cards
While there has been discussion about bringing such a system to Magic, it hasnt really taken off in a big way
For example, if a creature has three +1/+1 counters on it and two -1/-1 counters are put on it, state-based actions will remove two of each of those kinds of counters, leaving the creature with just one +1/+1 counter
