If you had 20 points to spend with no level restrictions, how would you spend them? Storm, Balance, Astral....or a mix of everything.....I think we can all benefit from each others' feedback!
As a start, train Ice to Tower Shield. I think that cost me 5 points. You only have to carry one shield and makes for a slimmer deck. I am Death (just turned Grandmaster) and with all the feints, blades, traps, etc it really helps. With creatures throwing big hits from different schools I always know that my tower shield is a half off sale! Not sure of many others. I have 7 training points saved up (for Astral magic?). I like my class spells and use them exclusively.
The blades from Niles in Krock Land and Sun Spells though Colossus. I don't think it counts but I also pick up Stun Block from Diego on Unicorn Way. That is all the extra spells all my current and future wizards get.
