I'm a level 52 Ice wizard, soloing the game. I'm currently about half way through Dragonspyre. When will I begin getting higher level cards? Is it when I hit Celestia? Currently my highest cards are the ice giant one (560ish damage) and the helephant (maybe 700 damage).
I also have an Ice i am leveling, currently the best spell you can get is a TC in the Bazaar called Blue Phoenix, 515 -595 for 4 pips. Its a solid hit that will get you through until you get Woolly Mammoth and maintain its usefulness after as a really good low pip finisher or minion killer. Enchanted Collosus will do more for damage wise but costs 2 pips more so if you can pick some of these TCs up
Just so you know your can now also train sun spells to boost your existing spells.
Strong level 50
Giant level 52
These spells are trainable in Celestia so you'll need someone to port you there. Or you can forgo that and just get the tc versions of them located in the bazaar.
