-- You choose which creatures controlled by the other player attack, who or what they attack, and how they assign their combat damage
For instance, Arcane Signet is common, whereas Loyal Drake is uncommon
The next card to be printed that altered a players maximum hand size was Cursed Rack in Antiquities , but instead of granting the controller of this artifact a limitless hand size, Cursed Rack reduced an opponents maximum hand size to four, meaning if they had more than four cards by the end of their turn, they must discard down to four during the cleanup phase
in a super creature-heavy deck (~40ish creatures) it's an okay success rate by itself but that percentage shoots up once you introduce topdeck manipulation like Sylvan Library, Cream of the Crop, and others

It's hard to say if these rough value ratios will apply to future metal cards, especially considering the low total values in question, but it's a good standard to keep in mind
