This is...an odd bug, so please bear with me as I explain. The bug works as follows:
1. Play Acceleration/Overdrive on any creature.
2. Adrenaline the creature
3. Play Sundial.
4. End your turn.
What happens is that instead of Acceleration/Overdrive giving 0, 1, 2, 3, or 4 power-ups (the last ones corresponding to Adrenaline's bestowing of extra attacks/actions on a particular creature), the creature gets
five power-ups in the same turn. This happens regardless of current attack and the creature it is used on.
Here's the issue. Acceleration works fine on its own. Adrenaline works fine on its own. Acceleration + Adrenaline work fine together. But as soon as Sundial gets added to the mix, things get REALLY screwy. So this leads me to believe that Sundial is the cause of the disturbance, and if this is the case I also believe the card needs to be examined and fixed ASAP.
Examples of the dangers of this combination:

A 20 point increase in just one turn...that's insane.
