Haven't played these in a while, it seems they haven't changed a lot. Anyways i absolutely wouldn't recommend running Sardonyx because it's way too slow, 2 summons and an attack for 1 search!? Overall I'd do the following:
-2 sardonyx
-2 reasoning [Sure if they call it right or wrong you Might end up with a summon of obsidian/amber or/and the fusion spell in grave but it's not reliable]
-1 turtle[slow]
-1 grandmole
-2 mirror
-2 D.prison
+2 d,d,r [get your fusions back and combos with obsedian/lazuli]
+1 redox easy to go effs and a level 7
+3 The thunder normal gem [more stablity and fusion versatility]
+2 tourguide +1 opitonal +1 kuribandit [revive rabbit/garnet..etc with digusto]
+1 TT ?
I used to run them very diffrently focusing solely on otk and with more on the aqua fusions but i hope that helped anyways.
