Less greedy Vanity's Stun. Running Seal of Orichalchos because why not, an extra 500 points puts my monsters above the 3000 mark, the downside isn't relevant, and I just want to play with the card. Dropped the Skystrikers, because you don't really get the full value off of Engage. Might be correct to play Engage just for deck thinning, but instead I freed up space for Instant Fusion.
Actually (somewhat) using the extra deck now with Extra-Foolish Burial and Instant fusion.
I decided to add back in a single Engage into Hornet Drones. Second copy is dead, but it gives me more deck thinning, potential card draw in theory, and makes tokens for 1000 less lifepoints than the alternative.
Dropped Engage for a One Time Passcode, since 2000 Def is appealing, and this way you don't brick with an Engage and a Hornet Drones when you need both special summons.
Going Terraforming over a second Mystic Mine. Even though it makes me weaker to Ash, it also lets me find Seal in matchups where the power boost is important, and it is functionally that second Mystic Mine still. The deck also isn't very weak to Ash in general, so making my opponent make the hard call on whether to bring hr in game 2-3 is appealing. (Other than finding Mystic Mine or Seal of Orichalcos, the only thing being Ashed is a search for Sauvaris)
I've gone up Preparation of Rites and Solemn Judgement for more protection maindeck. Those last couple slots aren't super important, I think 2 Solemn in place of Extra-Foolish Burial seems reasonable, the deck seems more versatile and this way is actually paying less life points than before.
