Whenever another non-token Spider enters the battlefield or attacks, create a 0/1 Black and Green Spider Egg Creature token.

At the beginning of each combat, you may sacrifice an Egg. If you do, put an Infestation counter on target creature. Whenever that creature deals or is dealt combat damage, that player sacrifices it and you create a 1/2 Green Spider creature token with Deathtouch and Reach.

Legendary Snake, please!

Reclamation Station

Artifact

Whenever an artifact or creature is put into your graveyard from the battlefield, that permanent gains Recover: . Each time you activate Recover, that ability costs one more until the end of the turn.

"We currently have Blasting Station, Grinding Station, and Summoning Station active. Salvaging Station has been renovated to better make use of recovered material. progress updates pending."

If we make another station, (Maybe 4/5, we'd have straight line of stations! Make one that doesn't currently exist! Or, make something that uses Pincher Tokens!

Kothophed, Soul Hoarder. Specifically his Magic: Origins art.... Interesting!

At the beginning of your next endstep, if that spell is still exiled, you may shuffle it into your library.

"Marine-Biologist Note #32-1A: A deep sea trilobite that frequents one of the only moderately survivable areas in the Trench; the thermal vents. Rich in bacteria and microorganisms, this trilobite seems to have evolved explicitly to feed and live in or around the vents. They deftly maneuver in the dark to hunt via some form of camouflage that is yet unknown. It seemingly appears and disappears at will, but more study is needed."

A return of the King of underused creature types! Make another one that would apply for this supposed Ocean Plane!

"New Phyrexia, once known as Mirrodin, had 3 layers. After the compleation of the plane, the Praetors sought to expand New Phyrexia to the 9 nine layers of their father's realm. Now, since the war on the multiverse, they accomplished their goal."
