**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.

**Influence**requirements over a set number of turns. The first column represents your opening hand when going first.

**Influence**to play any card with a cost of , namely

*. Follow the curve to see that your chances only increase with each additional draw.*

**Vanquish****on**

*Valkyrie Enforcer***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%.

*Icaria, the Liberator*are potentially as low as 70%.

**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

*“on Turn 4 or 5,” what we are really saying is “4 or 5 draws beyond our opening hand.”*

**Harsh Rule**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.

**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

*until Turn 5 or later.*

**Sandstorm Titan**Deck-builders are constantly asking themselves questions such as, “Have I included enough power to reliably cast

*when I want to?”*

**Channel the Tempest**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

*or the*

**Seek Power***. It even accounts for*

**Strangers****Ultimates**, Champion thresholds and other abilities that have a cost associated with them.

*not*accounted for?

**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.
