I autodueled through the Tower with my regular Warrior beatdown SD auto-duel deck (adding LP Boost Alpha just in case) and only lost once before the final available floor.
Still obviously need to go back and do like half the challenges, but still, it's far from impossible to just get to the end with autodueling.
Also, they are super-generous with LP Potions. You shouldn't have any real issues.
