Ancestral Vision is a powerful draw spell, but it has the drawback of taking 4 turns before being available. I can see this card in a shell with Jace, Vryn’s Prodigy and Goblin Dark-Dweller. Jace allows you to discard the extra copies and Dark Dwellers allows you to cast it for free from the graveyard.
Sword of the Meek will see play in control shells (most likely Blue White, with Ancestral Vision) or in Tezzerator decks. You can see my article about Blue-Black Tezzerator here: Blue Black Tezzerator
Thing in the Ice, most likely, will see play in existing decks where several spells and cantrips are cast. I think the best shells are Delver or Monastery Mentor style decks.
I think that Ricochet Trap will be a good sideboard card with Ancestral Vision and blue decks in the metagame. You can redirect Ancestral Vision to yourself to draw 3 card for only one red mana, or get a counterspell out of our blue opponent.
Thing in the Ice + Ancestral Visions
Here are few decks ideas
UR Delver in the Ice
Sword of the Meek
You can see my previous article about Blue Black Tezzerator here: Blue Black Tezzerator
Sword of the meek can be used in a control shell. I think it will be tried as a win condition in a Blue White deck in the future. But I want to share a Thopter Spy Network list that might help the deck with card draw when your thopters deal damage.
