This is a good deck and I feel bad that nobody has commented. So yeah. Comment. There's really nothing off the top of my head other than fetch and scry lands and maybe an Ajani Steadfast if you can get one. Even that is a little iffy but they actually do work as a one of when you have some mana to sink.

Thanks for the comment Ninjadude51. Yeah, I am planning on getting fancy lands sometime and I did just get a bunch of money for my birthday so I'm considering the investment (what better way to spend it?). Ajani Steadfast is an interesting idea. The +1 is the only ability I would likely use, but that is a very good ability in this deck. I will test it out and get back to you.

So, let me explain why I don't like Heliod's Pilgrim in this list. It is essentially a waste of a turn, where you could be buffing your creatures and getting in damage.

Errast thanks for the comment! That is a valid point but being able to fetch any aura is really valuable for this deck. Without that I probably have to remove the Aqueous Form and in turn remove the Fabled Hero, making this less fun, less spontaneous, and more like conventional heroic decks. But if you can throw a suggestion for a replacement at me I will definitely reconsider the pilgrim.

solrox38, I'm nopt sure why you wouldn't replace Heliod's Pilgrim with more Aqueous Form or Fabled Hero. They're cards you're worried you'd have to drop in, but you could just use the extra space to increase the number of those cards. I know in the description you mentioned not usually having more than one Aqueous Form out, but if you're going to go a strange and new U/W heroic route, you might as well keep in some old favourites, like Aqueous form.

Otherwise, I could highly recommend Daxos of Meletis, who is fun as hell. Or Ephara's Enlightenment, also fun as hell. Or both if you feel it would be better.

Ok that makes sense. I'll do some playtesting without Heliod's Pilgrim and I'll try out some of those cards and we'll see how it goes from there. Thanks a lot for your help!
