Excellent (8/10)
Epic Relics
Paid Relics
Players disagree about Janna's baseline strength. Some consider her early leveling experience difficult and heavily reliant on epic relics to function. While others find her to be an incredibly powerful engine capable of clearing the hardest encounters once fully equipped.
The Infinite Storm
Game Start: Create 7 copies of me in your deck. Champion Spells cost 1 less.
Power: Game Start: Grant a random spell from your deck Mark of Medarda. Create 4 copies of it in your deck.
Power: When you gain the attack token, create a random spell that costs 2 from your regions in hand. It costs 0 and is Fleeting
Strategy
This build maximizes Janna's spell-slinging engine. Echoing Spirit ensures you draw Janna consistently and provides cheap champion spells, which also prevents decking out during long encounters. Searing Brilliance offers immediate cost reduction and card draw, synergizing perfectly with her kit. Spellweaver's Symphony generates a 0-cost spell every turn you gain the attack token, allowing you to trigger her cost-reduction powers immediately for massive tempo swings.
Turn One Tempest
Power: Game Start: Drain 5 from the enemy Nexus. Play: If I'm Swain, refill your spell mana.
Plunder: I cost 2 less. I have +1|+1 for each different round you've damaged the enemy Nexus.- Game Start: Create 7 copies of me in your deck. Champion Spells cost 1 less.
Strategy
Designed for aggressive tempo, this build allows Janna to be played on the first turn. Swain's Raven Army damages the enemy Nexus at game start, instantly activating the Plunder cost reduction from Packed Powder. Once Janna is on the board, Echoing Spirit fuels her engine with discounted champion spells, enabling rapid board development and continuous removal.
Guardian of Zaun
Play: Shuffle 5 level 2 Champions into your deck and double their stats, then draw one of them.
Allied champions have +1|+1 and cost 2 less.- Allied champions have +1|+1 and cost 2 less.
Strategy
This setup leverages Janna's 4-mana cost to create a massive tempo swing. Oath of the Guardians shuffles powerful level 2 champions into the deck, while the dual Star Gems heavily discount them. Because Janna draws cards efficiently, you can quickly find and play these discounted champions to overwhelm the opponent.
Accessible Updraft
Round Start: Create a Fleeting copy of me in hand.
Round Start: Refill your spell mana.
Play: Deal 1 to all enemies.
Strategy
For newer accounts, this build focuses on sustained spellcasting and board control. The Grand General's Counterplan provides a fleeting copy of Janna each round, ensuring a steady supply of her champion spell. Archangel's Staff refills spell mana to cast these spells, while Ravenous Hydra offers immediate area-of-effect damage upon summoning Janna to help stabilize the board.
Other Relic Options
Excellent for drawing and discounting cards, facilitating infinite spell loops and providing critical early-game value.
Boosts the damage of her elemental skills like Howling Gale, turning them into reliable removal tools, though it requires a spell-heavy playstyle to maximize.
Highly effective in monthly challenges where you start with extra mana, though it can clog the hand in standard adventures due to excessive card generation.
This upgrade is considered low-impact because it does not trigger her 3-star power, making it a suboptimal choice.
Janna's relic flexibility is high, but she heavily favors items that provide cost reduction, card draw, or spell generation to fuel her engine.
Constellation
Janna is a powerful engine champion who excels at drawing cards and reducing their costs. Her primary challenge is surviving the early turns against aggressive opponents until her cost-reduction engine comes online.
What's Updraft?

+1 Starting Mana. When you play a cost reduced card, grant the weakest ally +1|+1.
What's Updraft? II
When you play a cost reduced card, reduce the cost of the top 2 cards of your deck by 1.Review
This power is the cornerstone of her kit, providing significant cost reduction that stacks with future draws. It transforms her from a slow setup champion into a relentless value engine.
Gameplay Tips
- Preventing Deck-Outs
Janna's aggressive card draw can easily lead to milling your own deck. Utilize her leveled-up Grifter's Deck spell to shuffle discounted copies of cards back into your deck, ensuring you maintain a healthy resource pool during longer encounters.
- Managing Board Space
Because Janna can rapidly reduce the cost of her units to zero, board space becomes a premium. Plan your summons carefully and use your own units for favorable trades to make room for more impactful plays.
- Exploiting Plunder
Even without specific relics, Janna's base deck contains easy Plunder triggers. Look for opportunities to deal early Nexus damage with your small units to activate Plunder effects and accelerate your game plan.
- Navigating Aggressive Encounters
Janna requires time to establish her engine. Against highly aggressive opponents, prioritize early blockers and removal spells over pure card draw to stabilize the board before attempting to execute infinite spell loops.
