Rune is very tiring mentally.
You need to calculate:
9 cards in hand
2 possible next cards from the draw
Hand space (max 9)
Spellboost decrements and battle damage combination
Time (dimension shift requires triple amount of time)
Board space (because kuon)
Earth sigil (sagelight teaching AOE)
Blaze destroyer's counter
Your lethal HP range (you have low hp because turn 1-3)

The good side:
If turn 4 no anne, you can just surrender without guilt, since you already lost.
