AI: AI uses Fist of Sun / Jodah, Eternal Archmage cost replacement on low-mana cards.

The cards mentioned in the title allow casting cards for {W}{U}{B}{R}{G} instead of their normal casting costs.
The AI used this replacement effect to cast a card that normally costs {G} for {W}{U}{B}{R}{G}, slowing down it’s own game plan.

This may be beneficial if the card has `Converge` or `Sunburst`, but not in the general case.

So the AI should not use this replacement effect if the the normal casting cost is a subset of {W}{U}{B}{R}{G} and it neither has Sunburst nor Converge.
