Описание: ❌ Most players lose games before the match even starts — in deckbuilding.

In this Union Arena Deckbuilding Guide, we break down the #1 mistake most players make when building their decks and how it silently kills consistency, tempo, and win rate.

Whether you’re prepping for locals, regionals, or just trying to level up your gameplay, this video will help you:

Identify common deckbuilding traps
Understand why certain card ratios fail
Build more consistent, competitive decks
Stop copying lists blindly and start adapting them properly

“What should I actually cut or add?”

…this video is for you.
