The only thing i dont like is the Spirit of the Ancient Golem in your build, the stats arent bad but it is too expensive for Shyvana early and the mana regen is a waste, if i was fed early i would prefer Wriggle's Lantern over it or stay with Madred's Razors and get my Locket of the Iron Solari or Aegis of the Legion asap since they both give more stats and are more team oriented.

Rest is cool

Your summoners... lol? Flash is very good. Why would you want to burn your only gap closer just to get away? Late game, you have to use your dragon very well because it won't be up constantly like it was early-mid game. Ghost should be recommended too. It's really good on bruisers. No mention of Randuin's? Sure, you have a ton of health, but those AD Carry's will be doing true damage to you late. You should get a HoG after Wriggles. You need the GP 10 in the jungle. It also builds into Randuins later. You should probably mention Aegis and FoN etc.

I do sometimes get a Sunfire Aegis, but it depends largely on the game- I included it in the items section!

Your build is just AWESOME!
only 1 thing: im playing shyvana seance the day she got released.
your items are missing a fire cape, this item is just awesome on shyvana
anyway you got a 1+ from me on the build and 1+ rep because you play shyvana and i thought im the only 1 XD

Nice build I could definatly use something like this!

I used to agree with you, but (especially after the nerf), I've started to prefer other items. I find the 18% crit and 830gp loss and the armor isn't that great for the total cost of the item.

+1 for effort. I'd really take an Atma's Impaler over Bloodthirster however. You can get both items by selling Wriggle's Lantern in the end.
