Warhorn Blast gives your whole team +1/+0 and trample until end of turn — a combat trick that punches through board stalls for a single red mana. The cost is real: it's a sorcery, so telegraphing it is almost unavoidable, and it does nothing outside of combat. In token-wide strategies, especially alongside Ranar the Ever-Watchful, the math on that trample clause adds up fast enough to justify the slot.

Ranar the Ever-Watchful
Ranar the Ever-Watchful generates a 1/1 Spirit token every time you exile a card from hand or a spell you control gets countered, so it routinely fields a wide board of flyers — exactly the kind of go-wide attack where Warhorn Blast's trample grant punches through the last points of damage opponents think they've blocked cleanly.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | legal |
| pioneer | legal |
| standard | not legal |
| vintage | legal |
| pauper | legal |
| oathbreaker | legal |
Warhorn Blast is legal in Commander, Legacy, Modern, Pioneer, Vintage, Pauper, and Oathbreaker. In Commander it earns a look in token-aggro builds that need a finisher on a crowded board — turning a dozen small creatures into trampling threats for one mana is the kind of surprise that closes games. In competitive constructed formats it doesn't clear the bar: one-mana combat tricks at sorcery speed are too slow when opponents have interaction on every stack, and the effect doesn't trade up on cards. Pauper is the one non-Commander home worth mentioning, where aggressive token strategies occasionally want a cheap wide-pump, but even there Warhorn Blast competes with faster instants.

Price Context
Current price
$0.09 bulk tier
At $0.09, Warhorn Blast is deep bulk — you're paying for cardboard and postage, not the card. Bulk rares and commons at this price point don't hold or gain value, so treat it as a throw-in: grab a copy if you want to test the slot and don't stress if it gets cut.
