Cheers @i_b_TRUE! Funny you mention the similar lists; here's a quote from me back in January:
Cheers to him, and I like his changes. In the main he’s turned 1 Revoker into a Metamorph, which somehow I’ve never considered. In the board he’s turned 1 Kataki, 1 Cage, and 1 Plow into 1 Crypt, 1 RIP, and 1 Trinisphere.
Seems like we were developing similar lists in tandem! Obviously YMMV and I don't mean to sound pompous, but I think you and I have basically arrived at the correct 60. +1 Metamorph, -1 Revoker is a totally fine switch; obviously great for your Oath matchup, and getting to copy an extra Glowrider or Eldrazi can be killer. I stuck with Revoker primarily for its castability, but was also keeping it for Shops (Ballista) and PO (Top and Time Vault).
Agreed 100% on Glowrider. The card is just insane against Blue decks; getting 3 extra Thorn effects is one of the more compelling reasons to play this deck instead of Shops. Wingmare would be an excellent addition to the deck, but our manabase is trash and can't accommodate it. Plus, Glowrider is old frame!
Likewise agree that if you're in a Shops-heavy environment, this is not the deck to play. This weekend, I was on 12 pieces of Shops hate in my board and still lost the match. But assuming you can dodge that matchup, I agree that the deck is well-positioned against almost everything else in the format.
