Think first.
Then let them fight.

1. Pick a mode. Battle uses the five-card deck saved in your profile (edit it, your name and avatar from the lobby). Draft Battle drafts a fresh deck first.
2. Draft your match deck (Draft Battle). Both players pick at the same time, five times: choose one of four random units at your unit level (Commons appear most, Legendaries least; no duplicates). After each pick you see what your rival took, so you can counter it.
3. Draft together. Three picks per round from your match deck; four after a loss. Each pick has a shared 30-second timer. Each recruit adds 3 Common, 2 Rare or 1 Epic/Legendary unit. Every unit starts the match at Rank I: an Upgrade offer raises all your units of that type one rank (up to III), and later recruits of it arrive at that rank. Rare ×2 offers double existing copies.
4. Watch them fight. Units move freely from their starting lanes. Goslings deploys a flock of four birds per card. Spiderlings and turrets cost no draft slots. Field Medic can heal himself.
5. Adapt. Armies persist; combat summons and statuses reset each round. A loss costs a life; draws cost neither player a life. Eliminate the enemy and resolve remaining missiles to win. Mutual elimination or 75 seconds is a draw.

Private rooms connect two people. Solo mode always identifies its practice bot. Room progress lives in this server's memory.
