A brother's birthday card operates under special rules: too sincere and he'll read it out loud in a funny voice, too jokey and you've wasted the one day a year you're allowed to say the real thing. The move is both at once.
Twenty-eight options below, sorted by how much roast your relationship can carry.

Happy birthday, brother. We fought over everything and I'd still fight anyone for you. That's the whole contract, and it renews annually.
Send as a card →To my brother: you were my first friend, my first rival, and the reason I learned to run fast. Grateful for every chapter. Happy birthday.
Send as a card →Happy birthday to the guy who knew me before I was anyone and never once held it against me. Love you, brother.
Send as a card →Growing up with you was the best training life ever gave me. Happy birthday to my built-in best friend.
Send as a card →Happy birthday, brother. Wherever life scatters us, you're my home team. Always were.
Send as a card →You're the one person who gets all the references, remembers all the versions of me, and shows up anyway. Happy birthday — that's rarer than you know.
Send as a card →Happy birthday to my brother — living proof that the family's good looks weren't distributed evenly. Condolences and cake.
Send as a card →Happy birthday! I'd list your best qualities but the card only came with one side. Kidding. Mostly. Love you.
Send as a card →Brother, happy birthday! You've been embarrassing me in public since before I could walk. The consistency is honestly admirable.
Send as a card →Happy birthday to the reason I have trust issues AND excellent reflexes. Childhood with you was a full training montage.
Send as a card →Congrats on another year, brother. You're aging like fine wine: better with time, and best kept in a cellar.
Send as a card →Happy birthday! Remember: I know everything you did as a teenager, and Mom has a birthday coming up too. Gift accordingly.
Send as a card →Happy birthday to my big brother — first to try everything, first to fall off it, first to tell me how not to. You blazed every trail. Love you.
Send as a card →To the big brother who threatened my bullies and stole my fries: perfectly balanced protection. Happy birthday.
Send as a card →Happy birthday, big brother. Half my courage is borrowed from watching you go first. I'm keeping it, by the way.
Send as a card →You made growing up feel safer just by being ahead of me on the path. Happy birthday to my first hero — don't let it go to your head.
Send as a card →Happy birthday to my little brother, who I've been simultaneously protecting and tormenting since day one. It's called balance.
Send as a card →To my little brother: watching you grow into this actual impressive adult is my favorite plot twist. Happy birthday, kid. Always kid.
Send as a card →Happy birthday, little brother! You'll always be the baby of the family — the six-foot, employed, somehow-taller baby.
Send as a card →I was your first bodyguard, first coach, and first bad influence. You turned out great anyway. Happy birthday, little bro.
Send as a card →Happy birthday, brother. Same team, always. 🎉
Send as a card →Another year of being my favorite rival. HBD!
Send as a card →To the family's best plot line: happy birthday!
Send as a card →Happy birthday bro — first friend, forever friend.
Send as a card →Cake today, roast forever. Love you, brother.
Send as a card →Roast-then-real is the sibling formula: open with the joke that proves the history, close with one sentence you actually mean. He keeps the card for the second part.
Cite the shared archive — the fries he stole, the trail he blazed, the running speed he taught you. Specifics only a sibling holds are the whole value of the card.
'First friend, first rival' names the thing brother cards are always circling. Send it as bubble wrap he has to pop — annoying him slightly is on-brand.
One roast, one truth: 'You've been embarrassing me since before I could walk — and I'd still fight anyone for you.' The joke earns the sincerity.
Anchor it in evidence, not adjectives: 'you knew me before I was anyone and showed up anyway' says everything without a single greeting-card word.
