Rukarumel, Biologist + Scuttling Sliver + Basal Sliver + Training Grounds

Rukarumel, Biologist

Scuttling Sliver

Basal Sliver

Training Grounds

How it works

1. Activate Rukarumel by paying 1 due to Training Grounds and tapping it, creating a 1/1 Sliver creature token.
2. Activate the Sliver token using the ability granted to it by Basal Sliver by sacrificing it, adding .
3. Activate Rukarumel using the ability granted to it by Scuttling Sliver by paying 2, untapping Rukarumel.
4. Repeat.

This delightful little brew transforms Rukarumel, Biologist into a self-contained sacrifice engine by rewriting the very biological fabric of your board. Because Rukarumel makes all your nontoken creatures, spells, and cards Slivers of the chosen type, she naturally bestows the gifts of her adopted swarm upon herself—granting us access to the activated abilities provided by Scuttling Sliver and Basal Sliver. Training Grounds steps in to grease the wheels, reducing Rukarumel's token-creation cost down to a manageable single mana while Scuttling Sliver's untap ability lets her ready herself for the next iteration. By tapping Rukarumel to spawn a token, sacrificing that token for black mana, and using a fraction of that bounty to untap Rukarumel, you generate an endless loop of enters-the-battlefield, leaves-the-battlefield, and death triggers.
