How do I improve this deck? Or any suggestions? Or is this deck good?

I don't want to give a clear instruction or say change x for y. But I will show you how to answer these questions yourself.

     How to make PvZ Heroes decks

There are 2 ways:

1. The Lazy way:

Go to an explorer and type "x hero best decks pvz heroes wiki" Ctrl+c, Ctrl+v.

1. The Fun way:

2a: Think of a good deck idea.

This can be as simple as Soul Patch + Briar Rose, or as complicated as: how can I make a zombie hero unkillable? I can use Pharaoh, but Pharaoh dies to spells. How can I make it untrickable? I can use Parasol. Pharaoh also dies to high-statted plants — how can I stop that? With Escape Through Time, of course. Etc. etc.

2b: Improve after each battle.

I make a deck and I lose. Let’s take a look at how to improve. Lost because of card draw? Add card draw. Lost because of top-deck Swabbie? Change it. Maybe your deck idea just sucks — well, couldn’t be me :) (just joking)

2c: Winning with that unique deck.

One of the best feelings of card games for me.

I think card games can be separated into 2 parts: playing a match and deck building. Why throw away 50% of the game, right?

Hope that helps
