Drakes are a predominantly blue flying creature type distinct from Dragons. They frequently overlap with instant-and-sorcery strategies. Some grow according to the spells in your graveyard, while others provide mana, card advantage, or evasive pressure.
Talrand, Sky Summoner creates a 2/2 Drake whenever you cast an instant or sorcery, while Drake Haven turns cycling and discarding into additional flying threats. Drakes therefore fit naturally into several spell-heavy strategies even without extensive traditional typal support.
