Anyone played pvz 1 where you had to bring a seed packet to upgrade a plant?
For example,using lily pad->catail
In the game:how about: repeater 2/2 2 sun-> pea Gatling upgrade for 2 sun,repeater now does 2 bonus attacks
or how about Gargantuar 5/5 frenzy 5 sun->Giga-Gargantuar upgrade for 3 sun,make Gargantuar into a 10/10
These are examples of examples of the upgrade cards mechanic.These cards would only be able to use in the first phase for zombies-not tricks,cannot be used in teleport.This is balanced,despite upgrades being low cost,they have a massive RNG to it-drawing it out.Plus,when the card is used,your opponent would use tricks such as squash to take it out,destroying the card.However,since the card is cheap,it makes up for the instant kills your opponent might have.
This would be good of the game because...
1.We get to use back cards we do not normally use
2.Adds more of a strategy to the game
3.Better strategy than just spamming late game cards
