Pseudodragon Familiar

The pseudodragon of D&D is a housecat-sized wyrmling, and the design leans into that literally: a small evasive body that can lend its flight to something bigger. What matters here is the activated ability, a repeatable evasion-granter that costs per activation. Point it at a stalled ground beater and the board math changes: a creature the defender was happy to trade with on the ground becomes a clock they cannot block. Because the ability targets any creature and resolves at instant speed, it also plays defense, letting a grounded blocker reach an incoming flier it otherwise could not touch, or turning an attacker into a threat the opponent must respect whenever you leave mana up on your turn. The rate is deliberately modest (a 2/1 flier that does little on its own tempo), so this is a support piece rather than a threat: a mana sink that keeps paying out in the late game once the two-power body has stopped mattering. Its lineage runs through the familiar-style creatures whose relevance lives in the attached ability rather than the statline, and its particular contribution is converting flying from a keyword some of your creatures happen to carry into a resource you can spend on demand.
