I still think it should be, to an extent, but its nice to see more board wipe options either way
Mai's strategy was all about duplicating Harpies with Elegant Egotist to Summon Harpie Lady Sisters, and Legendary Duelists: Sisters of the Rose has brand-new cards to help you multiply your Harpies and reward you for playing with the classic Harpie Lady Sisters card
And that answer, unfortunately, is not much
Instead of having to draw a specific card dedicated to being a resource and play it each turn, or generating a set amount of resource as per Legend of the Five Rings, the game is a constant back and forth of giving and taking memory, trying to be efficient in your moves and denying your opponent as much memory as possible to use on their turn
Paying 1000 LP for a Special Summon is relatively important, but not as much is you consider this card can easily Synchro Summon a Level 5-8 monster or Xyz Summon a Rank 4
