Hi, I'm Harvey. I have been playing Magic only since fifth dawn and I've always been interested in bounce. So when I saw the SOK spoiler, I immediately started thinking. Hence, a deck that abuses Blood Clock and The Web of War:
 

61 cards
 

Creatures:

2 Boros Recruit

4 Boros Swiftblade

3 Diving Griffin

3 Homura, Human Ascendant

3 Screeching Griffin

4 Soul Warden

 

Spells

4 Lightning Helix

3 Seething Song

3 Bathe in Light

 

Artifacts

3 Blood Clock

4 Ronin Warclub

 

Lands

9 Mountain

11 Plains

2 Sacred Foundry (budget too demanding)

 

Explanations:

Well, basically I want to drop a blood clock as soon as possible, and while disrupting my oppenent I could also use in the web of war to take advantage of returning a permanant. Ronin Warclub is one of my favourite additions as it really fits the theme because my creatures come into play alot theoretically. Screeching griffin and Diving griffin and most importantly Boros Swiftblade can make it hard for my oppenent to block my attacks. Homura is the best creature in my deck. Not only does it have a high attack power, my oppenent will be very hesitant to block it as it boost my creatures attack once it dies. Bathe in light can protect my creatures, but it can also make my creatures unblockable. However, what worries me is the centrepiece of the deck as it costs quite a lot of mana. Perhaps there can be some improvements. Thank you so much.

First of all, you're making a big mistake with Seething Song.  If you play the Song in order to get something out,, what happens if you have to return it to your hand for the Clock?  That's devastating.  What's called for here isn't one big burst of mana, but a steady flow of it.  Something that will give you extra mana more than once.  Replace Seething Song with Boros Signet.  This will soften the impact of having to recast your creatures turn after turn.
