This is to be expected as there are an innumerable number of characters across the games, but here it makes me question the larger set design
More than any other color, mono-black has staples that can fit in just about any black-using deck, regardless of its game-plan or construction
With this in mind I started looking at different effects for each of the colors
There's no "once per turn" restriction, and it's great that it triggers even if tokens enter on an opponent's turn
It doesn't copy whether that Equipment is tapped or untapped, whether it has any counters on it or any Auras or Equipment attached to it, or any non-copy effects that have changed its types, color, power and toughness, and so on
Designer Notes: Send your artifacts into battle and watch your commander explode with value, uncovering new power from the top of your deck
