so i think i've found a way to manage to fit some threats into the card manipulation:

next version of that deck:

// 60 Maindeck
// 31 Artifact
4 Lotus Petal
4 Mox Opal
4 Voltaic Key
4 Grim Monolith
4 Temple Bell
2 Aetherflux Reservoir
4 Paradox Engine
4 Thran Dynamo
1 Urza’s Blueprints

// 4 Enchantment
4 Future Sight

// 4 Instant
4 Force of Will

// 16 Land
4 City of Traitors
4 Ancient Tomb
4 Saprazzan Skerry
4 Seat of the Synod

// 5 Planeswalker
2 Tezzeret the Seeker
2 Tezzeret, Agent of Bolas
1 Jace, the Mind Sculptor

it's still a fragile deck, but it could actually support chalices out of the sb.
