I don't have premiums so i'd have to sub the paragons, squadron hawk, and hall of triumph
Hawks can easily be visionary, Jade Mage, and/or more Pegasus.
paragons can be +1 Banisher, +1 Triplicate, +2 inspired charge
actually I just realized something. I could cut jade mage? I havent been using its ability much. I notice you don't run it at all so the idea only now occurs to me to cut it from mine.
You asked about Jade Mage.
First I want to refer to your all or none approach.
Usually, a certain card in a deck have diminishing marginal utility, the more you play of a card, the less utility the extra copy will bring you. Usually it comes from the odd to draw more than one from the card, but sometimes it comes from other reasons. For example, in my golgari I play 1-of
reclamation sage because I have many ways to tutor him, revive him and reuse his etb - but I really don't need an extra copy.
lord of the unreal in MM have DMU with a big derivative, but the 4th copy is still worth including. You surely won't run 30 if you could, but something like 6-7 would be optimal.
Jade Mage ability is indeed underwhelming, paying 3 mana for 1/1 is subpar, and you practically use his ability when you have nothing else to do. I think 2 mana is usually the 'market' price for a 1/1 with no card disadvantage. Since it is not terrible to have this option, and I need exactly one Mage to have this option, I personally use 1-of in a build with no phantom generals. 2-of in a build with them. Non premium - if I had premiums, I wouldn't play them.
