Could you please give feedback on ^? Main things to consider PU, and that all of the powerful combos you can do with it have a lot of separate cards involved.
The Core of the idea is the effect:
"Any spell or skill that affects this card will also affect other Holy Runes."
The "up to 5" and "you control" clauses are unnecessary and do not have obvious thematic justifications.
This ability is primarily balanced by equal effect for positive and negative effects. However the current notes exclude certain negative effects resulting in less inherent balance. I would recommend removing this bias. Without that bias the positive and negative effects tend to cancel out.
CC would turn into Mass CC. Lightning would deal 5 damage to each
Mass CC would turn into incredibly large Mass CC. Thunderstorm would deal X damage to each
Buffs would turn into Mass Buffs. Blessing would add +3X attack total
Something important to remember is Buffs would get 1 attack before CC could be used. As such the stats should start subpar.
Fractal and Mitosis have enhancing effects on the original combo. Fractal increases the number of Holy Runes by ~6 each use. Mitosis increases the number of Holy Runes by the number at the time of casting per turn. Parallel Universe does not affect any Holy Rune therefore it does not trigger the ability.
Summary of Enhancers:
Fractal + Blessing + 2 Holy Runes: ~ 8 Blessed Holy Runes for 10
|9
+ 3
|2
+2 cards + cost of 8 Holy Runes
Mitosis + Blessing + 2 Holy Runes: ~ 6 Blessed Holy Runes for 5
|4
+ 3
|2
+2 cards + cost of 6 Holy Runes
Summary:
Remove the clauses and the buff bias, forget about Parallel Universe because it never had an effect and nerf the stats drastically.
