Zur (EDH / Commander)

A voltron / toolbox build for Zur.
Not meant to be competitive, just good in a casual environment.

My picks for the toolbox:
Phyrexian Unlife, in conjunction with Solemnity, almost gives immortality. The latter also shuts down experience, +1/+1 and infect decks.
Aegis of the Gods gives protection against targeted discard/sacrifice spells.
Rest in Peace effectively counters graveyard strategies.
Tainted Remedy gets rid of lifegain decks.
Trespasser's Curse kills token decks on sight.
Darksteel Mutation and Imprisoned in the Moon get rid of those scary creatures, planeswalkers and lands.
Detention Sphere is a good prison piece, also effective against tokens.
Ghostly Prison and Propaganda do well against combat-based play.
Mystic Remora is, in multiplayer, a ridiculously good card draw engine, especially if dropped on the first few turns.
Nevermore is excellent against strong commander-based play and combo decks.
Deafening Silence counters storm and combo decks.
Spirit of the Labyrinth does well against heavy draw.
Last but not least, Suppression Field is a good protection against many combos and, of course, all planeswalkers.

Updating details...

Throne of Eldraine updates:
Fabled Passage: good cheap fetch
Mirrormade: cheap and versatile alternative to Copy Artifact, it doesn't make me miss the old Copy Enchantment
Arcane Signet: the new best colored mana rock, replacing Darksteel Ingot to lower the mana curve
Deafening Silence: replaced Rule of Law, good 1-mana drop
