Cryptic Annelid

Hellbent — This creature has shadow as long as you have no cards in hand. (It can block or be blocked by only creatures with shadow.)

Transfigure 1BB (1BB, Sacrifice this creature: Search your library for a creature card with the same mana value as this creature, put that card onto the battlefield, then shuffle. Transfigure only as a sorcery.)

Fortified land has indestructible. Whenever fortified land becomes tapped, target creature gets +1/+1 until end of turn. Fortify 3 (3: Attach to target land you control. Fortify only as a sorcery. This card enters unattached and stays on the battlefield if the land leaves.)

At the beginning of your upkeep, put a spore counter on this creature. Creatures you control have "Remove two spore counters from this creature: Create a 1/1 green Saproling creature token."

Choose target attacking or blocking creature. Scry 3, then reveal the top card of your library. Judge Unworthy deals damage equal to that card's mana value to that creature.

Whenever a player casts a noncreature spell, each of that player's opponents may draw a card.

At the beginning of each player's upkeep, destroy target nonartifact creature that player controls of their choice. It can't be regenerated.

(This land isn't a spell, it's affected by summoning sickness, and it has "T: Add G.")
