Mika

Source of Water I: The 1 wave add-on for this Epiphany can allow it to situationally allow around +1-3 AP versus base source, depending on your other sources of wave from effects like Tactical Analysis.

Source of Water II: After you recover, you have a 0-cost 2 AP Source of Water. This condition is typically very easy to fulfill and is valid for all Source of Waters if duped.

Source of Water III: Now, the source has the [Retain] feature and will boost your other cards’ healing. These are some great utility add-ons, but the loss of AP is often hard to justify these bonuses for, mainly because AP is one of Mika’s main draw-points.

Source of Water IV: In Chaos, this is an extremely strong card during a run as it allows you to heal stress. However, it can feel rather lackluster outside of Chaos, where stress is much easier to manage.

Source of Water V: The card now gives 3 AP but is [Exhaust]. This can be great for OTK or other low-turn content where you need a lot of AP but only for one turn.

Neutral: Target Neutral Epiphany: Morale 1.
+1 Morale Neutral Epiphany can be an amazing choice as it allows you to get buffs alongside the AP and healing, making Mika a more versatile support. The downside is that there are likely preferred options to use if using Mika in this way, as the main draw she has is giving a lot of AP through Epiphany options like Source of Water I and Source of Water II, rather than buffs.

Divine: Which Divine Epiphany to go for will depend on what your team needs and which Epiphany you chose, but here are the main ones to look out for if you have spare Save Data: Draw 1, -1 Cost Reduction.

Blessing of Waves I: The ability to convert her healing into shield allows you to give a very substantial shield with this card, giving her more defensive utility than just healing.

Blessing of Waves II: The 1 wave add-on for this Epiphany allows it to sometimes be free to play. However, it is a card often kept for its defensive utility, which makes this variant’s comparative lack of defensive value harder to justify in comparison to Blessing of Waves I.

Blessing of Waves III: The buff on this card allows you to multiplicatively boost your next card’s healing based on your AP, which can be quite nice for a high base ratio heal. However, it’s probably preferred to have the card itself heal more with other Epiphany versions.

Blessing of Waves IV: This Epiphany converts the healing into Fixed Damage, which can bypass certain defensive buffs like Damage Reduction and Fortitude; however, you lose a lot of the possible healing and defensive utility for this damage that cannot easily be improved or buffed because of its fixed nature.

Blessing of Waves V: This Epiphany is 0-cost and can give a lot of healing to save you in a pinch, but it forces your turn to end because of the [Finale] tag, which can lead to forcing awkward decisions. For example, you might need to heal to live an incoming boss hit, but doing so with this card will also end your turn.

Neutral: Target Neutral Epiphany: Draw 1.
Neutral Draw can be an amazing boon on this card, as it more easily justifies keeping it since there won’t be any draw concerns with playing it.

Divine: Which Divine Epiphany to go for will depend on what your team needs and which Epiphany you chose, but here are the main ones to look out for if you have spare Save Data: Draw 1, -1 Cost Reduction.

Tactical Analysis I: This gives an additional heal, which can be nice for activating effects that require heal or recover. Unless there is an effect based on using a heal-skill you need this for, it is generally a rather low value addition, though.

Tactical Analysis II: This Epiphany gives a healing bonus multiplier. Because Mika already heals a lot, this isn’t recommended as a first choice.

Tactical Analysis III: This Epiphany gives a healing bonus multiplier. Because Mika already heals a lot, this isn’t recommended as a first choice.

Tactical Analysis IV: The 1 wave add-on for this Epiphany allows it to sometimes be free to play, or more accurately, give ⅓ of an AP for an additional AP every 3 cards played. While this can have higher potential than any other AP source on Mika, it can be rather inconsistent as it needs to be played before other cards and has a lot of cards to play for full value on it. Moreover, this has amazing synergy with other wave effects, lowering the threshold for how many cards must be played before you get the extra wave value.

Tactical Analysis V: Because this Epiphany allows you to thin your deck after Turn 1, since it goes away once played, it’s a nice passive buff to healing that will not hinder your draw after Turn 1. Generally, this is the go-to choice because of its consistency and not having to be drawn every turn.

Neutral: Target Neutral Epiphany: Morale 1.
Neutral Epiphany for +1 Morale can be a nice additional buff, especially with Divine options like Divine Draw, making it easier to cycle.

Divine: Which Divine Epiphany to go for will depend on what your team needs and which Epiphany you chose, but here are the main ones to look out for if you have spare Save Data: Morale/Resolve (Tactical Analysis V), Draw 1.

Whirlpool I: Now, Whirlpool heals based on the number of targets, which makes it not only a damage card but also a very conditional but high heal-Potential card as well.

Whirlpool II: If there are at least 3 targets, the card is now free. But Whirlpool is a damage card that scales with attack. Generally speaking, Mika does not build much attack, if at all. So it will do very little damage.

Whirlpool III: Allows you to buff your healing based on the number of targets hit, but it only works for the next card played and the 2 AP cost for this buff is quite hefty. Moreover, Whirlpool is a damage card that scales with attack. Generally speaking, Mika does not build much attack, if at all. So it will do very little damage.

Whirlpool IV: The card becomes free for the Turn upon 4 recovers, but Whirlpool is a damage card that scales with attack. Generally speaking, Mika does not build much attack, if at all. So it will do very little damage.

Whirlpool V: The card now heals and receives a damage buff based on heal; however, it is hard to scale this damage buff to a level where the damage is meaningful.

Neutral: Target Neutral Epiphany: Morale 3.
3 Morale can be an amazing boon and allow Mika to buff you a substantial amount, if you can afford the AP cost.

Divine: Which Divine Epiphany to go for will depend on what your team needs and which Epiphany you chose, but here are the main ones to look out for if you have spare Save Data: Vulnerable 2.
