You need to deactivate Unlimited Mana in the menu, and just use the Defense and Attack buff, you only get unlimited mana when YOU HOST THE GAME in PVP, make sure you host the game, check the unlimited mana hack before the game starts, when the cards spawns, check your energy, if you have full energy, deactivate the unlimited mana hack, and play normally, if the cards spawns and energy is still filling, YOU’RE NOT HOSTING THE GAME and no hack will work, accept your defeat and repeat.
Pd. If you’re not hosting is not necessary to deactivate the unlimited mana buff.
For PVE, in boss fights you need to slow the f*** down, boss imitates the same buff you have, uncheck the unlimited mana and attacks hacks, activate the enemy no mana hack, and spawn some cards, check and uncheck as necessary, yet the defense and attack hack should be enough to win a match if your cards are leveled enough.
I hope I explained myself, if not I’ll try to make a video.
