Svella's Rolling Thunder

A fast Gruul Brawl deck led by Svella, Ice Shaper that ramps with cheap mana creatures, builds a wide aggressive board, and converts extra mana into Icy Manaliths and 4/4 Trolls before finishing with Embercleave or Goldspan Dragon.

Svella, Ice Shaper makes Icy Manaliths that tap for two mana, so each Svella activation accelerates you into more Svella activations and 4/4 Trolls. Rhythm of the Wild makes every creature uncounterable and gives riot, turning each threat into either a bigger body or an immediate attacker. Embercleave gets cheaper with each attacker and turns any large trampler into a double-strike lethal threat. Ram Through, Blizzard Brawl, and Domri's Ambush use your creatures' power to remove blockers while Poison Dart Frog's deathtouch makes fight spells one-sided.

Keep hands with two to four lands and a one- or two-mana play. A hand with a mana creature plus a three-drop is a snap keep. Mulligan hands with fewer than two lands, hands with only expensive spells, and hands missing red or green by turn two. The deck wins by curving out, so do not keep speculative one-land hands.

Early game, deploy mana creatures and hasty one- and two-drops to pressure life totals. Midgame, land Svella and build Manaliths, or resolve Rhythm of the Wild and aggressive enchantments to snowball. Late game, use Svella repeatedly, cast Goldspan Dragon for Treasures and card advantage, then suit up Embercleave on the largest trampler for a double-strike kill. Keep a fight spell or protection spell for the final alpha strike.

The deck is soft to mass removal because it commits hard to the board. It can struggle against heavy flying decks and protected enchantment engines. Counterspell-heavy opponents are mitigated by Rhythm of the Wild but not solved by it. Fast combo or lifegain decks can race you when you draw an all-ramp hand.
