Auras that grant reach have always lived a defensive double life: they nominally pump a creature, but the +1/+3 split here tells you which side of combat the card cares about. The toughness boost is the headline, turning a midsized body into a wall that survives the trade while reach quietly closes the air lane that ground creatures can never cover on their own. The trouble is structural, and it predates this particular Aura by years: an Aura is card disadvantage waiting to happen, since a single piece of removal answers two cards at once. That math is why combat-trick reach (an instant that grants the keyword for a turn) usually wins the design argument over a permanent like this one. The trick spends one card to get one effect and leaves no lingering target behind, so the opponent never gets the two-for-one a sitting enchantment hands them. What the permanent buys in return is repeatability across multiple turns of blocking, which compounds only when the board stalls long enough for that to matter. As a piece of green's defensive toolkit, it answers a real gap (ground creatures cannot block fliers, and green's interaction with the air is famously thin), but it answers it in the most fragile package available, which is why this style of effect rarely graduates beyond filler.
