One of the defining characteristics of modern competitive arena battlers is that they are never truly 'finished'.

This article explores the philosophy behind balance changes, the introduction of new mechanics, and what the future holds for the genre.
The Philosophy of Buffs and Nerfs
If a card is being used in 40% of all top-ladder decks and has a 58% win rate, it is mathematically overpowered and will receive a 'Nerf' (a reduction in stats, like lower hitpoints or slower attack speed).

The developers must be incredibly careful, as a tiny 4% damage reduction on a single spell can completely destroy an entire deck archetype.

To keep the game fresh and generate revenue, developers consistently introduce brand new cards with entirely unique mechanics.

As a player, your job is to quickly identify the weakness of the new card before the general player base does, allowing you to easily counter the inevitable influx of people testing it.
