Shadowverse

The mechanization of Radix is a bit much; if it weren't for that, I'd probably ditch it too. But it's not always possible to find and play them in time, and you're always trading with Enchantments and Analyzing, so that's why I decided to try bringing Sapphire back.

Although, I'm a bit of a weirdo and I play with three Sylphs in 2019 (they say such a deck is called "aggro portal" and doesn't play Deus, but to me, that's even more of a perversion).

I've seen and even tried a few games with it, and again, there's Lee Shenna, and the associated drawbacks, and I didn't like it. The board isn't sticky, there are no buffs, no pressure, it's just garbage.
I also saw a very similar list without Lee Shenna, but with that neutral-omen Widow. I can't try it myself because I don't want to craft it, but it's probably a more sensible deck, as Shadow plays with it.
I also crafted two new powerful Sylphs for myself and put them in non-artifact decks, but they've disappointed me so far. When you need them, they don't appear, and when you don't need them, they clog up your hand. And the acceleration on them is kind of useless most of the time. Although, they say it works well in "aggro" or "pup" decks.
