Ekko: Predict into discounted Oath champions

Play Ekko to add doubled level-two champions to the deck, then use Predict to find and strengthen them. Two Star Gem copies help turn those large draws into affordable plays.

This six-star version focuses on the champions created by Oath of the Guardians, rather than repeatedly summoning the original champion for the strike-and-item engine. You gain several possible finishers and give up some consistency in finding a particular generated spell or another copy of the original champion.

Oath of the Guardians

Play shuffles five level-two champions into the deck, doubles their stats and draws one of them. A revive or an Ephemeral summon without a Play does not repeat this trigger.

Two Star Gem copies

Each copy gives allied champions a stat bonus and reduces their cost by two while its bearer is in play. Rare duplicates are allowed. Together they discount the other champions by four, in addition to applicable created-card discounts.

The Gems don't discount their own bearer in hand before he reaches play. Plan how to afford the initial four-cost champion instead of treating the whole trio as an opening cost reduction for him.

Mulligan for a playable opening, the champion and access to Time Trick. Develop enough defense to play him safely, then inspect the first champion drawn by Oath before spending your remaining mana.

The two-star created-card discount helps the shuffled champions. At six stars, seeing a unit in a Prediction doubles that particular copy's stats. You can choose to draw it now or leave it in the deck for later; seeing one copy doesn't apply the same upgrade to every card sharing its name.

Use Time Trick and your other draw tools to locate a useful affordable finisher. The Oath draw itself is not a Prediction, so it doesn't automatically receive a six-star Predict doubling. Check the current hand cost while the Gem bearer is alive, and don't rely on the discounts surviving his removal.

Favor inexpensive Predict effects, mana and defensive answers that let the first champion stay on board. A powerful shuffled champion still needs board space, an available attack or a useful effect for the situation. More expensive random finishers aren't always better than the one you can play immediately.

Avoid loading additional draw onto every already-drawing spell. A full hand can burn the champion or attack tool you were searching for. The shuffled champions dilute the original deck, so this plan isn't built to hit the same champion repeatedly with random item effects.

Echoing Spirit with Oath and a single Gem adds more original-champion copies and cheaper champion spells, while giving up one Gem's discount. Its created copies also benefit from the two-star discount. That version gets back some access consistency at the cost of making the other champions more expensive.

Oath comes from Gold Reliquaries; Star Gem is a Rare-pool relic. If the Epic is missing, use the existing entry-effect guide rather than equipping two Gems without a reliable way to find other champions.
