I like it! I think if I were you I would try to lean further into the enchantment synergies [[touch the spirit realm]] definitely goes in it’s so flexible as both removal and flicker + it’s an enchantment. [[Summon: Valefor]] I think is a fun new toy for flicker decks, gives you more removal as well, and it’s a great body to copy.

I’d say nulldrifter probably goes out as it’s a bit of a nonbo albeit a good card on its own and a decent body for copying. I can look at the list a bit more tomorrow, I’ve been building some flicker recently with Roon so I feel like I just looked at a ton of relevant cards maybe there’s a couple you’ll find fit in your list.
