I'm mixed on this, but a lot of people have been having luck.
Glacial Chasm seems better. I haven't had much of an issue with Solitary Confinement though.
I agree
With the amount of combo, RiP Helm is something easy-ish to pull off.
Also, RIP shuts down other decks besides, blanks Deathrite Shaman, Knights of the Reliquary, Loaming Lands, Tarmigoyf for people who play it
Some unusual sideboard tactic for lands and death and taxes is City of Solitude. This blanks rishadan port and flickerwisp or aether vial tend to be much worse when you can't flash it in. Tried to Also, suppression fields make D&T more difficult
Mixed. If you make land drops, it can be easy. If you're land light, it can be tough. Flickerwisp targeting your forest with Utopia Sprawl and Wild Growth is pretty abysmal. Replenish seems to be good in this matchup. Councils's Judgement can hit your Enchantresses or anything even with a Sterling Grove out.
I think Enchantress is still favored, but you play it differently and want to make all your land drops. Don't enchant a single forest, don't enchant non basics, if you have Sphere of Safety out, still pay for a Elephant Grass (or discard for Solitary Confinement) if your opponent could swing lethal if it disappears. They don't have much enchantment removal, so it's a matter of preventing them from attacking and building up stalling for your win con.
Doomwake Giant makes this game pretty easy if you can protect it with a Sterling Grove. Dread of Night is a good sideboard card if the meta is plagued with D&T. I like Leyline of Sanctity, but it might be over boarding. Mirran Crusader with a Sword of Fire and Ice is pretty strong. Engineered Plague is tempting but usually bad. Naming Horror stops Phyrexian Revoker (Soldier hits Thalia and Recruiter, Elemental hits Flickerwisp, Cleric hits Mom, Spirit hits Spirit of the Labyrinth). Naming Human is going to give you a bad time.
Ethersworn Canonist and Spirit of the Labyrinth make the game tougher. They can protect them from removal with Mother of Runes.
Cast Out seems pretty good. Doomwake Giant if you have black splash. Choke is old, but is really strong now, as is Carpet of Flowers (except when they have Leovold out).
If you're running Solemnity, I think you should run Crop Rotation. Crop Rotation into Dark Depths or Glacial Chasm is pretty strong. I don't like Crop Rotation for Serra's Sanctum.
Banishing light you can cast if your opponent has no permanents. Cast Out has flash (draw a card if Leovold is out), is 4cmc (get's around Sanctum Prelate on 3), and can be cycled.
Nay. They canctivate Sneak Attack at the end of your turn, and it untaps during their untap step.
Authority of the Consuls seems okay against Elves, but you don't slow them down much.
