The idea is to get Chronozoa out.
- Clutch of the Undercity can transmute for it
- Back from the Brink can return it from the graveyard.

After that:
- Manipulate it at instant speed with Hex Parasite
- Protect it with Lord of the Unreal
- Copy it with Quicksilver Gargantuan for 7/7s that turn into more 7/7s
- Copy it with Cryptoplasm; if the copy dies, it creates copies of Chronozoa with the copy ability.
- Paradox Haze removes more counters

Otherwise:
- Krovikan Mist loves more Illusions
- Runed Stalactite makes things into Illusions
- Trinket Mage searches for Hex Parasite and Runed Stalactite
- Summoner's Bane interacts, and also creates an Illusion
