Hi david22, all the active skills and leader skill are not effective in the arena battle, but the guild lab buff is effective. In an arena battle, the overall attributes (HP, attack, recovery, etc.) of the two rivaling cards will be evaluated and compared and the one with higher overall attribute will win.
Enjoy the game!
