Tannuk, Steadfast Second

Haste anthems usually ride on a bigger creature, a throwaway rider that reads as "your team can attack the turn it enters" and little else. What makes this Kavu load-bearing is its warp grant, which turns that haste anthem into a repeatable trick rather than a one-time speed boost. Warp lets a red creature or artifact enter cheaply but not permanently: the warped permanent leaves for exile once the turn winds down, so a body cast on your main phase gets exactly one turn on the battlefield before it goes, then can be recast later for its full cost. On its own that is a tempo tool: pay less now, pay again on your terms. Under a lord that hands everything else haste, though, the warped creature does not sit there summoning-sick, waiting to matter. It arrives, swings, connects, and only after combat does it bounce away, which means the discount buys an attack instead of a preview. The 3/5 stats are built to survive combat and keep the anthem online rather than to lead the charge, a defensive frame around an aggressive engine. That inversion is the design: the commander granting haste is the least hasty thing on the board, a steadfast second that pushes the front line forward while holding the back. Aiming warp specifically at artifacts and red creatures keeps the enabler pointed squarely at the deck it was built to lead.
