I dont really have a reason for it being so expensive except that its in low supply to be honest
Each sword costs mana to cast and mana to equip, granting the equipped creature +2/+2, protection from two colors, and unique abilities that trigger upon dealing combat damage to a player
Black is one of the most popular colors in Commander, and as long as one player is running it, theres a good chance youll get some card draw here
While the most obvious choice is to pair it with Unwinding Clock to reuse its abilities on each of your opponents turns, you can also run other clever synergies, like putting Curiosity on it for extra card draw
The fact that the lands she animates do not gain permanent +1/+1 counters or have vigilance is yet another sign that WotC did learn from the worst excesses of 2019 not being able to switch your brain off and uptick her forever makes all the difference when it comes to producing an engaging subgame for both players
What has been more controversial among players is that, despite the high prices, the cards do not represent major changes in design or playability
