Bone Party is decent but it's actually not that make or break. Bone Party is an extender 90% of the time in MD because people aren't using that many targeted negation. Might surprise you to know though that Bone Party makes effects fizzle for Memento anyways.
They didn't limit Tatsunootoshigo, the best extender in Memento. It's basically good enough
Meanwhile I had an even win% today in Plat1 with Meme Goblins, which is by far my lowest win % in a very long time. Why? 5 out of 8 duels came down to who resolved Maxx C (I was on 3 of them) and I bricked on a 40 card deck with very few bricks in 2 duels, completely fumbled 1 duel that was playable vs. Lab, and then got wrecked going 2nd vs. Argostars, which I had basically 0 idea how to combat outside just nat draw Harpie's I guess.
Had even coin flip wins and bricks on 2 going firsts. Happy days. Meanwhile I got 3 wins against Blue Eyes of all things. Had a really cool sequence where I did the Bone Party pierce on my 5k guy and TTT steal their Tyrant for 8100 dmg total into Maiden and the Link-1. Hilarious stuff, but that was one of my Maxx C wins, which diminishes the win quite a bit
