Although this event is common, it is not a very popular event. However, all players are encouraged to consider the following strategy to maximize the results, since the strategy's principles are useful for other events. Most/All major events do require players to spend energy to earn rewards.
Players should bear in mind that most/all of the following strategies are ideal for players, who are in time zones, which are 1 or more hours different than UTC time; but the principles still apply. The amount of Mover and Shaker rewards earned depends on the time zone that a player lives in, but the amount of Thirst for Activity rewards is predictable and consistent across most time zones.
Hero Wars gives each player 420 points per day [i.e.: 10 points per hour + 60*3], whether or not there is an event. The event is 3 days long, and will allow a player to spend a total of 1260 points, if he spends energy accumulated only in the time period.
If he consumes these energy points by failing at, or succeeding at, campaign missions, then he should be able to achieve 2 Mover and Shaker rewards per day, and 3 Thirst for Activity rewards.
A player could store up energy from the day before and the morning before the event, so that he could get another Thirst for Activity reward. For example, level 60 player could save 120 points before the event starts, and then use them up as soon as the event starts. These 120 points, plus this day's 60*3 energy, plus 420 points on each of the 2 full days, plus 60*3 energy on the last day, plus any energy that he gets every hour which isn't already factored in, will allow him to spend a total of 1560 energy points, which would give him the 4th reward.
This strategy would give him an additional Mover and Shaker reward on the first day, also. This strategy could be customized further, allowing him to earn more Mover and Shaker rewards, and other unrelated rewards. Because he saved 120 points from the day and morning before, he could spend a maximum of 540 points, which would be 10 points away from an unrelated daily quest, which would reward him glyphs. He could save 130 points from the day before instead.
On the 1st full day, he could spend 150-290 points. In other words, he should save 130 points for the next full day, so that he could earn the unrelated reward for earning 850 activity points the next day. This strategy would prevent him from earning the 2nd Mover and Shaker reward on the 1st full day, but the 850 activity point reward is much more appreciated among experts.
At the start of the 2nd full day, he should immediately spend the 130 points that he saved, and plus the normal 420 points, as planned. For this event, it would earn him the 2nd Mover and Shaker reward, as normal, and it would also earn him the 3rd Mover and Shaker reward, which would bring him 3 more Mover and Shaker potions in total for the 2 full days, compared to if he had not saved his energy. According to this strategy, all energy should be spent at the end of the 2nd full day.
On the last half day, he should spend points that he earns every hour, plus the 60*3 energy points, earning him the 2nd Mover and Shaker reward.
