[Brainstorming] Chisei, Heart of Oceans

[Offler]

Once again discussion on topic "Look at this bad card" ended up in a discussion "this would be crazy" :) The discussion started when we were trying to found a way how to play Glacial chasm as long as possible. Here is the result:

Chisei, Heart of Oceans
(Based on Hungry Hungry Heifer)

Clockspinning
Paradox haze or Eon hub Depending on amount of cards with cumulative upkeep.
Power conduit

Decree of Silence
Arcane laboratory or/and Erayo, Soratami ascentant and/or Ertai, Wizard adept

Removal of counters
Dark Depths
Unstable mutation
Biting tether
Chronozoa

Cumulative upkeep
Glacial chasm
Illusionary presence
Mystic remora
Musician
Illusionary terrain

Persist
Glen Elendra archmage
River Kelpie
---
Cauldron of souls

Undying
Geralf's Mindcrusher
Relentless skaabs
Stormbound geist


For now its just a bunch of cards without any deeper idea of winning. It offers few locks and control - especially Decree with Chisei and Laboratory...

Is there any other way how you can imagine Chisei based deck to work?
