Ominous Roost

Casting from the graveyard is normally a one-way transaction: you spend the yard down and get a spell for it, nothing more. This enchantment attaches a bonus to that act, so every spell recast from below the battlefield also mints a flier. The trigger is deliberately agnostic about what you cast, only that it originated in the graveyard, so any flashback card, any escape spell, any effect that recurs a spell from the yard feeds it without demanding a specific keyword. The Birds are where the design turns aggressive. They fly and they can block only other fliers, which means they contribute nothing on the ground defensively but everything on the attack: an evasive clock that widens each time you loop a spell. This looks like a value engine and plays like an air raid, chipping one, then two, then three a turn while the graveyard keeps restocking the sky. The token on entry is a hedge against an empty yard, keeping the card from stranding dead in hand before the recursion comes online. It wears its condition without disguise: pair it with a shell that casts spells twice as a matter of course and it snowballs into a genuine threat; drop it into one that never fills a graveyard and it makes one Bird and quits. That transparency about its own ceiling, no floor propped up by hidden upside, is what keeps the build-around fair.
