I thought that after you hit level 68 then there isn't much more to learn spell-wise. Astral schools are great but they don't inflict damage. So I thought about a side school that could be cast by anywizard no matter what type. So I came up with the gold school which is like an astral school except it can do damage. It could appear in the next world and it could aid you. Also, I know that wizards that aren't life or don't have life spells might not be happy because all they have is pixie to heal so I can put in healing spells too. Here's the first spell.
Golden warrior: pip cost 9: 200 damage to target enemy and 500 life to you. Summon golden warrior minion. Golden warrior minion is: minion with 500 health and has the cards... cyclops, kraken, sprite, elemental blade, balance blade, pheonix and vampire.
last night I made up a ton of new spells for the gold school and got the idea it could be in a group of spells like astral spells so I'll post that soon.
