About the Eternal Power Calculator
You will gain a competitive edge in Eternal by maximizing the chances of playing your cards on curve.
Getting under the hood and optimizing your deck's power base is
the best way to ensure that you can play the cards you want, when you
want to play them.
The Eternal Power Calculator is a deck-building tool that
visualizes your odds of drawing enough Influence and Power
based specifically on the cards found in your deck.
How it works
Import a deck and the visualizer will display a graph showing the
probability of meeting specific Influence
requirements over a set number of turns. The first column represents
your opening hand when going first.
Charting
Influence
In this example you can see that on Turn 2 you have a better than
90% chance of drawing the right Influence to play any card
with a cost of 
, namely Vanquish.
Follow the curve to see that your chances only increase with each
additional draw. But what if you want to play Valkyrie
Enforcer on Turn 3?
is a higher Influence cost, so your chances decrease.
Fortunately this deck builder (2017 ETS World Champion camat0) has
included enough Justice sources in his power base
that the odds are still pretty good - nearly 80%.
Draws vs. Turns
Here the chart tells us that after 7 turns our odds of hitting 
to
play Icaria, the Liberator are potentially as low as 70%.
However - assuming you will play at least one aditional draw card such as Quarry before Turn 7 - your
chances of meeting Icaria’s steep
requirements improve, as represented by columns 8 or 9.
Beyond the first turn, most decks include additional card draw. Even
though we might speak of wanting to play Harsh Rule
“on Turn 4 or 5,” what we are really saying is “4 or 5 draws beyond our
opening hand.”
This becomes even more important as the game goes on. You draw at
least one card per turn of course. But ideally you will also draw some
extra cards along the way.
When using the Eternal Power Calculator, it helps to
get in the habit of thinking of number of draws rather than number of
turns. Power Odds Table
Influence is only one of two costs in Eternal that are associated with
playing your cards. To see the whole picture, we must also consider
Power.
For simplicity, we generally assume that at least one Power
card will be drawn for each turn, and our Maximum Power
will increase at a consistent rate.
Realistically, however - that only happens when luck is on our side.
It is often just as true that we will miss a Power
drop and not be able to play Sandstorm Titan until
Turn 5 or later.
Deck-builders are constantly asking themselves questions such as,
“Have I included enough power to reliably cast Channel
the Tempest when I want to?”
The Power Odds Table removes the guesswork by
factoring in both Power and Influence
costs for every card in your deck. This includes neutral cards such
as Seek Power or the Strangers.
It even accounts for Ultimates, Champion thresholds and other abilities
that have a cost associated with them.
What is not accounted
for? The probabilities displayed by the Eternal Power
Calculator are quite accurate and will help you gain a
better understanding of your deck. But for the sake of simplification,
a couple of factors are not accounted for mathematically: mulligans
and prerequisites.
These two factors influence the probabilities in different ways, and
when combined they come close to balancing each other out - so the net
result is minimal.
The Mulligan Phase Deciding whether or
not to keep your opening hand is a strategic decision in Eternal.
If you choose to re-draw, your starting hand is guaranteed to include
either 2, 3 or 4 power cards (with an equal chance of each).
This raises your chances of having more Influence to
start with - so (generally speaking) your odds may be ever-so-slightly
higher than what is actually depicted on the charts in the Eternal
Power Calculator. Pre-requisites On the other
hand, some power sources have a Power cost
associated with them. Seek Power and the
five Favors are the most obvious examples.
The Eternal Power Calculator considers any card that
increases your Power to be a Power
source when determining probabilities. But it does not consider the
sequence in which cards are played.
In other words, including Vara's Favor in
your deck will increase the overall chances of reaching your desired
Shadow Influence costs. But because it can not be played
until Turn 2, if you draw Vara's Favor instead
of a Power card your true odds of achieving 
on Turn
1 will be ever-so-slightly lower than what is represented
on the charts.
