Dwarven Castle Guard

Two-for-one aggression compressed into an uncommon-shell body: the 2/1 attacks like a proper early beater, and when it trades, it leaves behind a Hero token so the exchange never falls flat. The math is what makes this worth a slot in white weenie shells. A 2/1 into a bigger blocker or a removal spell normally means you lose a card and the tempo; here the death trigger converts that loss into a fresh body, keeping the board wide for the anthem effects and go-wide payoffs that this kind of deck is built around. The trigger cares about death specifically, not leaving play, so it rewards throwing the Dwarf into combat and pays out through sacrifice outlets and burn just as readily as through blocks. The Hero token itself is a nod to the source material's protagonist framing, but structurally it does the same work as the creatures that leave a Saproling or a Thopter behind: it turns a fragile attacker into a resilient one and softens the sting of trading down. Nothing about the rate is flashy. What it offers is a floor: a two-drop that refuses to be a dead trade, which is exactly the reassurance a curve-out aggro deck wants from its cheap slots.
