Clarion Conqueror is a sturdy 3/3 flying blocker that stabilizes against their fast creature curve (Slickshot Show-Off, Pompous Battlemage, Callous Sell-Sword) while shutting down activated abilities on cards like Drake Hatcher's incubation removal. Curious Farm Animals blocks early aggression and gains life when it dies, supporting your lifegain plan. Starscape Cleric can't block, which is a real cost against this tempo-aggro deck, so trim it. Liliana the Faultless is too fragile against their cheap removal like Burst Lightning.
