I delayed going to the center, but on turn 126, I definitely took the Dragon Grail with 9 Gray Dragons, 30+ Vivs, 3+ Angels, and the rest. Crag and Gunnar leveled up amazingly, but my opponent couldn't handle the third consecutive unfavorable game. GG, ready for a rematch!
After going to the center, there was another zone right away, and after that, it was impossible to break through to the Efreet (there were also Angels standing there).
GG, thanks for the game!
