*MTG Question* What support cards would work best in my type 2 mono-white exalted deck?

You don't want any kind of enchantments to put on individual creatures as you will be 2-for-1'd all day long.. Honor of the Pure, i agree isn't very useful in an exalted deck. Looks like you have 24 slots filled.. that leaves room for 8 spot removal cards like p2e's, oring, pacifism, etc and with that many exalted creatures, you need a big guy.. Preferably somone with evasion. Battlegrace is good and at 5 mana isn't as expensive as it may seem. Baneslayer is really good but seems like you wanna be fairly budget on this deck, so Baneslayer might be out of the question. Maybe Guardian Seraph? I dunno, i think Battlegrace is probably best. That would fill up your 4 other slots.. Goes with the theme anyway as well..
