Players constantly argue over whether randomness adds exciting unpredictability or ruins the integrity of esports.

However, it still exists in subtle ways that can completely alter the outcome of a very close match.
Initial Deck Shuffling
The most prominent RNG element in card-based battlers is the initial four cards you are dealt at the start.

Professional players build their decks specifically to minimize the chances of a truly unplayable starting hand.
Never run a deck that is too heavy.Don't panic if your starting hand is bad.It happens to everyone. Unit Targeting and Pathfinding
Sometimes a unit will retarget unexpectedly due to a micro-movement by another troop, completely ruining your defensive setup.

Relying on a unit's aggro range down to the exact pixel is risky because tiny bumps can alter their trajectory.
