The deck also has a small Golem subtheme: since Ich-Tekik, Salvage Splicer pumps up all our Golems when our artifacts hit the graveyard, we have some spicy Golem inclusions like Cradle Clearcutter which makes more mana as its power increases, Geode Golem which can help cast our commanders, and Triplicate Titan which is a powerhouse finisher
Getting to tap down your opponents team is a nice effect to have, but not one worth playing without wanting the other mode
Well need to pick carefully, since the transformed version, Leyline Surge, gives us a beginning-of-upkeep trigger to put a permanent card from our hand onto the battlefield
Final Fantasys subset, Through the Ages, is a true home run, giving us very useful cards with some wonderful/iconic/nostalgic art
Arguably even more important than that, however, is Sephiroths ability to counter the Broodscale combo matchup
