Stormcaller Sovereign

Eris, Roar of the Storm is a commander built for late game cadence. She arrives with a high casting cost that collapses quickly as you fill your graveyard with instants and sorceries. The built in flying and prowess make her both a tempo piece and a threat generator; she turns each successive spell into pressure while offering evasion for her 4 4 frame.

In practical play she rewards spell diversity and sequencing. Cast cheap interaction early and watch her cost drop, then leverage the second spell trigger each turn to spawn 4 4 dragon elemental tokens that themselves benefit from prowess. The card fits any deck that blends stormy control and token midrange, and it reads like a plan: stack spells, drop Eris, close the sky with dragons and repeated prowess triggers.
