Lol the game clearly states: "Card attack and defense stats up 100% for 7 days. The Upgrade Potion and Upgrade Potion+ items cannot be used simultaneously."

Of course you can't use multiple potions at once that way you could boost your dmg to do practically unlimited dmg taps without any buffs. This would break the game.
