Deck Name: Slivergeddon
-----------------------------------------------------------------------------------------------
Format: Legacy
Deck Type: Tribal Aggro
Colors: Five-Color (WUBRG)
-----------------------------------------------------------------------------------------------
Description

"Slivergeddon" embodies the ultimate tribal synergy of Slivers, combining relentless aggression with resilient survival tactics. Every Sliver enhances the swarm, granting abilities that make the army stronger, faster, and more adaptable. With access to every color, the deck ensures explosive starts, disruption, and inevitable dominance over the battlefield.

This deck thrives in both 1v1 and multiplayer Legacy, capable of overwhelming opponents with sheer numbers and versatility. With powerful anthem effects (Predatory Sliver, Sinew Sliver), evasion (Galerider Sliver, Cloudshredder Sliver), and protection (Crystalline Sliver, Teferi’s Protection), it becomes nearly unstoppable. Sliver Overlord provides tutoring and control, while mass recursion like Storm of Souls and Patriarch’s Bidding ensures the hive never stays down for long.
