I've been having a kind of similar idea, using Young Pyromancer instead of his more seasoned brother, giving you the Risen Reef effect for each instant and sorcery. I'm definitely still tinkering, but if you can manage the money, Manamorphose gets some pretty good mileage in. I want to know how this works out for you.

legendofa ya, I have had Young pyromancer in the deck before thinking the same thing. I just don't run enough spells. The spells I do have are just to try to protect my combo pieces. I have been play testing this alot. Talking with my friend after some games we thought that a humas's mana base may be good here and just take out the spells. I think it may be good and bring in Aether Vial as well. I'm not sure, have not had that much time to play test this week. I will be making changes depending on how i feel this is playing out. Also on a side note, the deck does feel fine, as I stated it can win on turn 4. the problem is that those hands are rare to get. I am also finding out what hands are better to keep and the Serum Visions do help a ton. I may make another version of this deck that has a Sneak Attack like effect with it, using Incandescent Soulstoke in it. To get Tyrant of Discord or Omnath, Locus of Rage into play with a Risen Reef and just go off. It would almost be an instant win at that point if i can sac them and use my effects to keep going ( getting a land triggers the Risen Reef witch gets another elemental and so on. Still working on it. I think in that deck young pyromancer can work because im trying to protect my lord and drop Big Omnath. So all a work in progress. Ty for the comment and like !
