Snatch Steal, Future Fusion, and Return from the Different Dimension are all easy to fit in. Bottomless trap hole comes back (for a short period of time) due to the recursion fear of Phoenix/Zombies, so actually quite a bit gets removed. The 2 DDA and DDWL automatically removes 3 dragons for you too. 1 tech copy of RftDD is not that bad at all.
Snatch Steal is a definite must, because the world runs around it now.
Also, you may want to throw in 3 Cyber Dragons to speed up the summoning. They aren't dragons, but they're another target for Future Fusion, as well as some attempt for the deck to catch up to Samurai deck's insanity opening hand (Cyber Dragon + 1 Six Samurai + Grandmaster immediately... cry).
Sakuretsu should really be switched to Bottomless trap hole now, because it's more likely than ever, Sakuretsu gets killed by snipe hunter, six samurai and mobius before it can do anything. Also, again it goes against the recursion talk (that will die very soon.)
Consider sidedecking Lightning Vortex, because we're at the time of swarm-mania o_O; Hydroggedon, gravekeeper's spy, six samurais and gadgets got the upper edge at the beginning of this format, and lightning vortex is best used to wipe them all at once, even if it cost you the card (hence why it's not bad in the sidedeck.)
EDIT: leave PoA out, cause Dragon's Mirror will remove the 5 dragons PoA also need for Five Headed Dragon. If you really need draw power, use card troopers as that thing is pure evil (but card trooper is far more CC than theme...)
