Tide Turners

Tide Turners is a set of cards released in Plants vs. Zombies Heroes. The update introduces 120 new cards, 25 (as of now) new Heroes, and a new trait, Pre-Strike.

Story
When the Hero-Tron went off on the mainland, a shipwrecked Zombie on an island in the middle of the ocean saw the flash go off--specifically where it came from. Using this knowledge, he and his Zombie buddies teamed up with the local flora to craft a large vessel to get as many Zombies and Plants to the mainland as possible.

Meanwhile, an intimidating pirate and his crew have just finished picking clean the distant land of China and are heading home to keep what they've managed to carry back to the boat. However, when he arrives, he's met with an unexpected deal with Dr. Zomboss--a deal that he wouldn't refuse even if he could.

New Heroes
The set includes 25 new Heroes. Each Hero can use cards from the classes they lead. What sets these Heroes apart from standard Heroes, however, is the fact that they have 1 class from each side. Each Hero is assigned to a side but can use cards from the other side that correspond with their second class. For this reason, they can be referred to as "Hybrid Heroes".

The set will also include 25 other Hybrid Heroes that are counterparts to the current 25. However, these counterparts have access to a completely different set of superpowers.

New Superpowers
With the second set of Heroes, a new set of 30 Superpowers have arrived. These Superpowers, in a similar manner to Beta-Carrotina and Huge-Giganticus, are unique to these Heroes only. However, they share these superpowers amongst themselves in a similar manner to the original 20 Heroes.

Note: The cost is implied to be "1".

New Cards
These cards are standard cards and act as any normal card would. They also behave properly should they be used by a Hybrid Hero.

The update also adds a new trait, Pre-Strike, specifically for the Zombie class. If a Plant is on the same lane as a Zombie, that Zombie does a Bonus Attack before combat.
