MTG Salvation

I’m building a casual kitchen table Sliver deck built around Sliver Gravemother I’m going to run Sundial of the Infinite and Teferi’s Veil as ways to indefinitely keep the token creatures generated by Sliver Gravemother. What other cards are out there that let me keep those tokens indefinitely?

Obeka, Brute Chronologist, time stop, Discontinuity anything that ends the turn.

Dominus of Fealty and Teysa, Envoy of Ghosts.

The Master, Multiplied would be REALLY good in this scenario. Also using cards that changes Eternal Scourge, Misthollow Griffin, and Squee, the Immortal into Slivers via Arcane Adaptation, Conspiracy, and Maskwood Nexus could work as well since you can cast them from exile and they gain Encore from Sliver Gravemother since they're Slivers and searchable with Homing Sliver. You can also use Ashnod's Altar / Phyrexian Altar as a free sac outlet for recasting Eternal Scourge, Misthollow Griffin, and / or Squee, the Immortal from exile with extra mana.

Doc Aurlock, Grizzled Genius can help you recast Eternal Scourge for 1 or just UU / RR with Misthollow Griffin / Squee, the Immortal. Food Chain could work with this as well especially in tandem with Ketramose, the New Dawn for card draw and a life gain outlet. Day's Undoing gives you a Wheel of Fortune effect while ending the turn to keep your creature tokens with Sliver Gravemother. Blade of Selves can serve as a backup in case Sliver Gravemother is in your Command Zone and has a hilarious interaction with Kokusho, the Evening Star especially If you make Kokusho a Sliver.
