Crimson Mage

Haste-granting bodies belong to a small, repetitive design family, and this one sits at the dim end of it: a repeatable activation stapled to a fragile 2/1. The job is straightforward, hand a freshly cast creature a hasty attack the turn it lands, so a topdecked threat can swing before the opponent untaps to answer it. The trouble is that the engine asks you to commit a two-drop and then keep mana open every turn to feed it, a steep tax for an effect that does nothing unless you have a new creature each turn to point it at. That is the structural mismatch: haste only matters the turn a creature enters, so a repeatable enabler is only worth its slot beside something that produces a steady stream of fresh bodies, a token maker or a flood of cheap threats. The repeatable activation is the only thing distinguishing it from the one-shot pump tricks that grant haste as a rider, and repeatability cuts both ways here: it is flexible, but it never threatens to do more than what it says, and the deck around it has to supply every reason to care. A baseline Human Shaman with no other text leaves that work entirely to the rest of the list. Built as glue for an aggressive red shell that wanted to keep pressing new attackers through, it fills a slot rather than defining one.
