In Plants Vs Zombies Heroes, you're not going to be playing cards. You'll directly be playing with the creatures that appear on the battlefield. Each creature has its own distinct number of suns that is usually one of seven depending on how useful the creature is. Each turn your maximum number of suns will go up one point just like in Hearthstone.
The biggest noticeable difference between Plants Vs Zombies Heroes and the original card game is that you can put your own units in any number of different paths on the game board. How well your units are placed is just as important as which creatures you choose.
In total, in Plants vs Zombies Heroes you use more than 300 different creatures. At the beginning of each battle, you can personalize your hand of creatures, although you can also choose to set this to automatic if you want to get straight to playing. Plants vs. Zombies is a great game that allows you to play in single player campaign mode or have even more fun playing PvP. Just like any other EA game, the graphics are fantastic.
