Pack Mastiff

The pump reads to every creature you control named Pack Mastiff, which always includes the one activating it: a lone copy can crack itself open for repeated red mana, growing a point of power at a time while it swings. That self-inclusion is the quiet hinge of the whole design. On a single copy it is a middling mana sink, a way for a red deck that has run out of gas to convert surplus lands into damage. On multiples it compounds, because one activation lifts the entire kennel at once, and each additional body multiplies what your mana buys. What keeps the scaling from running away is the shape of the buff itself: +1/+0 only, all reach and no armor, expiring at end of turn. Every point you pay for evaporates before your opponent's turn, leaving the pack exactly as fragile as it was, so the ability rewards spending mana on offense the turn you plan to attack rather than banking it defensively. This is the old redundancy-as-payoff school of common design, where the ceiling is a direct function of how many identical copies share the board and the floor is a workmanlike beater with an outlet. The reward structure is deliberately narrow: it pays off aggression and quantity, and the only deckbuilding demand it makes is more copies of the same name.
