Uhhh,,,,i don't find it necessary to have high end cards to win at all....... I am beating decks with infinitely more legends (I have several rare or below decks that have 60% or 70% winrates, even vs ranks 30+).
I think it is necessary to think about your win conditions, which a LOT of card players fail to realize when they build a deck. Most players fall into the trap of "o i think this card is good, o that one is good, let me put that in" rather than having a really clear strategy on how to achieve victory. Here are some simple tests when deck building
1. Q: Do you know when your deck is the strongest?
A: when you build your deck, are you looking for a balanced deck, where at each point of the game (early, mid, late), you will have the same amount of power on the board, and you whittle your opponent down slowly? Are you looking for an aggressive opening, and then snowball in the mid game in order to avoid a late game? Are you looking to just control and clear the board early game, build a small board mid game, and then annihilate your opponent in the late game? These are very important in deck building
2. Q: Which cards are you looking for in your starting hand vs which zombies/plants?
A: You have to evaluate different situations. A LOT of this comes from experimenting, facing different plants/zombies will call for different starting hands. This doesn't mean specific cards, but specific things you look to do
3. Q: Which cards are my winners, and when I should place them?
A: You need to consider the situations really carefully when you put these cards in. For example, a gravestone, 5 brains, do I play super phat beets, things like that.
There are a lot of questions that are necessary to build a good deck and play well.
