Playstyle Tips and Strategy/How to Play
Mika functions as an AP battery and healer for your team, and she's really good at it. Her core strategy revolves around managing Wave stacks, accumulating them through her abilities to generate bonus AP when needed.
Focus on duplicating her zero-cost cards, particularly Source of Water and Tactical Analysis. These cards let you heal and build Wave without spending resources. Prioritize the Wave epiphany on Source of Water and the Upgrade epiphany on Tactical Analysis for enhanced healing output.
Wave Management:
Build up to 2 Wave stacks and hold there until you need extra AP for expensive, high-impact plays. Since Wave resets after hitting 3 stacks, timing when to claim that bonus AP is crucial, don't waste it when you can't capitalize on the extra action.
Strengths:
Mika excels at resource generation and team sustainability through exceptional healing and AP production, making expensive strategies viable. Her low-cost cards mean she operates efficiently without draining your action economy.
Limitations:
She doesn't provide offensive buffs or card draw, and her personal damage is minimal. Her full potential unlocks with duplicates, making her more effective as you invest in her development.
Bottom line: Use Mika to fuel your team's actions while keeping everyone healthy, carefully timing your Wave triggers to maximize high-value plays.
