Blox Cards Wikia

The cards on this page are likely to be different ingame. The general principles of differentiating cards.

So. You want to know how to figure out which cards are good. Here's how.

1. Comparisons

The most crucial thing to learn about card power is that it is entirely relative; The power of a card is based on the power of other cards.

What this means is that, in order to determine card power, we need to compare cards to other cards.

There are three forms of comparisons for every card: Strictly Better/Worse, Situationally Better/Worse, and Non-comparable. We'll be going over all three today.

(Generally speaking, better cards will lead to you gaining a card advantage over your opponent. A card advantage is when you have more cards in your hand and field combined than your opponent.)

Strictly Better/Worse

In normal playing scenarios, if a card is better than another card, that card is strictly better.

(Don't rely on this method. If a card is strictly better than another in every possible scenario, then it's likely to be changed)

For example, let's compare AsrielMemer to ColonelGraff.

AsrielMemer Luna.png
ColonelGraff Card.png

About AsrielMemer About ColonelGraff
Cost: x4 White, x1 Blue Cost: x1 White
Health: 400 Health: 300
Power: 400 Power: 0
Effect: When this card is cast: Draw a card. Effect: When this card dies: Draw a card.
AsrielMemer is strictly better than ColonelGraff.

As you will see in the Example bellow, Effects can determine how powerful a card is, While ColonelGraff's effect is much better than AsrielMemer for the price point, Asriel still has a bigger statsline meaning it can stay alive for more time instead of dying like ColonelGraff (Which is the whole point of the card,)

It should be noted that "strictly better" cares about cards being better in normal playing scenarios. There are scenarios where SnyFort (2W2B H400/P400) is better than FuryBlocks (2W H200/P400), but we are concerned with just standard, normal playing scenarios.

Slightly Better/Worse

These cards are roughly even in power. Circumstance is more important in determining which one is better.

For example, let's compare TZSara to Blotnik

TZSara Luna.png

About TZSara About Blotnik
Cost: x3 White Cost: x3 White
Health: 600 Health: 400
Power: 300 Power: 300
Effect: During your end step: All players gain 100 Life. Effect: Whenever this card attacks: it gains 200 Health.
Depending on the situation, TZSara or Blotnik is better.

Whilst TZSara has better stats, Blotnik has something that TZSara doesn't: An effect that allows it to gain Health. This means that when you attack with Blotnik for the first time, its stats increase to exactly the same as they would have been had you cast TZSara instead.

However, TZSara's effect should not be discounted. There are numerous cards with effects that trigger when you gain Life, such as NatzHakz and iSpaceDonut, to name a few.

Because of this, there are a number of circumstances where TZSara is better than Blotnik, and a number of circumstances where Blotnik is better than TZSara.

TZSara is better than Blotnik if:

  • Your opponent could take down Blotnik before it attacks.
  • You have cards that would benefit from TZSara's lifegain.

Blotnik is better than TZSara if:

  • Your opponent has a fighter or several with low Power, like a Doge or Final Tree
  • You lack any cards that would have benefited from TZSara's lifegain.


Some cards have entirely different purposes, and should not be compared in order to determine card power.

For this example, let's compare Bobaman1 to Luck o' the Lobsters.

Bobaman1 Card.png
Luck o' the Lobsters Luna Fixed.png

About Bobaman1 About Luck o' the Lobsters
Cost: x4 White Cost: x4 White
Health: 400 Health: N/A
Power: 400 Power: N/A
Effect: When this card is cast, if your opponent controls at least 5 fighters: Deal 400 damage to all enemy fighters. Effect: Cast only if you have 1500 or less life. Deal 4000 damage to all fighters.
Even though they have similar effects, Bobaman1 and Luck o' the Lobsters have entirely different purposes.

First off, ask yourself the purpose of these two cards.


  • His effect deals a medium amount of AoE damage to your opponent's side of the field only.
  • His effect can only be triggered when the opponent has 5 or more fighters.

Hmm... A medium amount of damage won't destroy all fighters, but it will destroy most weak fighters. Aren't there several decks that love to spam fighters onto the board? Take the Doge (Group), for instance. Most of their cards have less than 400 Health, and summon Doges.

Bobaman1, then, is an anti-aggro fighter that punishes the opponent for overextending.

Luck o' the Lobsters:

  • Deals a very high amount of damage to every fighter on the field. This means that, when you cast it, you don't want to have more fighters on the field than your opponent.
  • It can only be cast when you have 1500 or less life - typically when you are about to lose.

Sounds familiar? An empty board, your opponent preparing to finish the job... That situation, the 'endgame,' is where this card thrives.

Luck o' the Lobsters, then, is a lategame card that gives you the chance to make a comeback.

To solve the problem of noncomparables, you would have to add a rider to your question. If you were to ask yourself which card was better in a normal deck, it would be Luck o' the Lobsters, as its condition can be met by every deck. If you were to ask yourself which card was better in a Control deck, it would be Bobaman1, as the Control deck's slow speed would allow your opponent to easily gather fighters.

2. Factors of Power

Whilst comparing cards is all good and dandy, what are the traits that make cards better?

  • Cost: If a card does the same thing as another card for less, it's strictly better. (Note that icon costs got weird after Storexit dropped. White icons now affect the number of cards you can play each turn, and all other icon types affect when you can play a card. There's a whole blog post about it.)
  • Card Advantage: "Draw/Give yourself a card" is one of the best effects in the game. Cards that add cards to hand, cards that take multiple hits to kill, etc., all contribute to card advantage. Anti-Zanzel Lifeloss makes excellent use of a variety of card advantage sources in order to grind down the Priestess Zanzel AI.
  • More Health/Power: If it can destroy higher-Health fighters, or take more hits from lower-Health fighters, it's generally better. NOTE: Power is valued at approximately double that of Health.
  • Utility: If a card can do many different things and is applicable in many different situations, it can be considered good. The Crystal Cycle is an excellent example of this.
  • Buildaround: Buildaround cards, such as SlingshotJunkie, get much stronger if you base your entire deck on exploiting them, or "build around" them. Buildaround cards are almost always found at lower rarities.
  • Weakness Management: Cards that allow decks and colours to manage their weaknesses, such as Bobaman1 in a Control deck, can be very powerful.
  • Resilience: Some cards have special effects which make them harder to be removed via effects. 1337 is the granddaddy of this type of effect. Cards that are easy to remove are usually weaker.
  • Demands Removal: Cards such as The Stalker must be dealt with by using a removal spell. If you don't, you risk losing major amounts of card advantage. More on removal here.
