Surrak Dragonclaw helms a Temur big-creature midrange/ramp deck that flashes in beefy threats at instant speed, protects them from counterspells, and pushes overwhelming trample damage past blockers. You ramp early, deploy fatties on opponents' end steps, and turn excess power into lethal swings or finish with a stompy haymaker.
Built-in counterspell protection makes your key creatures resolve reliably
Flash lets you hold up interaction and ambush attackers or deploy threats at the optimal moment
Trample turns big bodies into reliable damage that chumps can't stop
Temur colors give access to the best ramp, card draw, and fight/removal spells
Does nothing against targeted removal, board wipes, or exile-based answers
No card advantage engine built into the commander itself
Vulnerable to flyers and evasive go-wide strategies it can't profitably block
Five-mana commander that competes with your ramp curve and can stall if drawn into a slow hand
