Outside of Mono-White Aggro, Origin of Spider-Man could see play in Standard Yuna, Hope of Spira decks, as well as in counters-matters decks if the Mono-Green shell has a decent reason to go into Selesnya
We have a new, fresh, never been handled by customers
Who are you running
Sidar's eminence ability provides a ton of power for the deck, smoothing out your draws throughout the game, letting you hit your land drops early and find gas late game, all while setting up Sidar's incredibly powerful reanimation combat trigger
And then we have a more oddball artifact with Machine Gods Effigy, which acts like Cursed Mirrors big, blue sibling
Also, a shout out to another 2 mana tap for a big effect Gate, Basilisk Gate which can pump up a Commander by a bunch in a Gate brew, and win much more quickly with Commander Damage
