Sphinx's Revelation

Looking for more of that "kill" card more than another way to draw since i can draw as many cards as i want every round once the combo is in place. Also looking for card suggestions for side board to round out the deck.

How about running AEtherling as your ''kill'' card. What do you think of Spellbook instead of Library of Leng ?

I like the swap for Spellbook , but AEtherling doesn't really fit

Walking Archive maybe to go with the Archangel of Thune and Horizon Chimera theme. Just a suggestion. I actually really like this deck and wouldn't change much. Your "story" sounds exactly like mine.

Spellbook is a very suboptimal card, as it takes up space in the deck and doesn't actually make an impact on the field. Reliquary Tower is a much more efficient option.

Thanks for you comment PhageTheUnbeatable,
I've debated this swap myself, and found Spellbook to be a reasonable alternative to Reliquary Tower because it doesn't use up my land drop for the turn, which can be costly when playing 3 colors.

To be honest I've debated pulling out altogether since it doesn't have much an an impact other than allowing me to have a fat hand.

Reliquary Tower does not "use up" your land drop for the turn; it is a free spell attached to a land, which is very efficient. I would suggest only running one Tower, as it does interfere with your mana base. As for the mana base in question, you should be running 4 Hallowed Fountain and 4 Misty Rainforest along with one more of the two shocklands you already have. I would also cut the 2 City of Brass and add 2 Horizon Canopy .

You might also want to run 4 Verdant Catacombs .

I'm liking Horizon Canopy a lot, nice suggestion as it fits perfectly into this deck. I was all happy till I saw how much it costs on eBay, totally insane.

I would even recommend a Laboratory Maniac Just in case you can not kill them with your creatures, you can use that as a win condition
