What determines the order of the arks when they jump in? I had a few battles just now. I noticed the opponents’ arks always go ahead of me. Say I detonated a minespider, I have vegetiger, speed 21, and he had chillqueen, speed 18. Why does my vegetiger enters into battle at 54TU and chillqueen 18 TU? I’m really confused about it! 
Good question. The same applies to the beginning of the battle where often an ark with lower speed goes first.
I think it’s about luck, making the PvP more variable. For example, 80% of players in master league use shadowstalker on line up, so who goes first? It’s about luck, sometimes player A sometimes player B. That’s the same with different arks. Maybe chillqueen with a speed of 18 has 5-10% to go first instead of vegetiger with 21 speed. That’s my thought
