I was thinking of mixing Cydarks with Dragunity. Cannon can send Javalin to the grave and Jav can SS itself when equipped to a Cydark for a Sync-5 play (Goyo). I'm thinking that the Extra might be too tight tho...
that would work quite nicely although the synergy with the equip spell wont be there and that is probably the key first turn synchro card in the deck! would be interesting to test though you could combo it with goyo chaser and the new level 5 duel a thon reward ( goes to 3000 atk when a level 3 is destroyed... kind of works with cyber dark!) but I could see a hybrid working purely just because of cannons plus 1 draw on destruction comboing that akyls with storm would be so satisfying!!!!
About how many gems did you take to dig your Dragunity stuff?
it took 174 packs... I had about 5000 gems saved and I have been grinding all of the rental deck stuff, and with the extra exp and duel orbs (been spending about 5 hours a day on this as soon as the box came out) they made me wait till 6 packs for the UR synchro :,( deck runs so much smother with it but I think you only really need that and stardust!
