Ryan Sinclair

Impulse-draw attackers have always fought a self-imposed tax: the spell you want to steal off the top is usually bigger than the digger will let you cast. The clever move is tying the cast cap to the attacker's own power. At 2/2 the ceiling starts low, which turns every point of power you add into two payoffs at once: better combat math and a wider band of spells the trigger can find and fire for free. A pump spell or an anthem stops being just a combat trick and becomes a cast-condition; growing the body is the engine, not a bonus stapled to it. The reward loops back on your own aggression, since the free spell you uncover is only ever as large as the attacker you were willing to build and swing.

The Doctor's companion tag then colors what all that value is for. As a Legendary Creature, Ryan can helm a deck alone, but the keyword invites a paired build where it becomes the aggressive, resource-generating half of a two-general partnership alongside a Doctor. Red rarely gets repeatable card advantage this clean, and pinning it to a combat trigger keeps the flow honest: nothing arrives unless the 2/2 is willing to walk into blockers first. The advantage exists only on the back of that commitment, contingent on the risk taken and on how much you invested in the body before the attack.
