Maybe a few strategy:
If you can draw all your deck this turn, and your hand is getting clogged by sundial (but otherwise you could start the combo) then just start it, and draw the remaining card afterwards.
Don't overdraw against Gods that need Chimera.
Against gods that doesn't need chimera, if you overdraw (but still be able to draw more that turn) and if you have enough quanta, you can play chimera (0|0 stats) and continue your draw.
Don't hesitate to play multiple sundials, especially when your deck has reached 10. Use them for the draw. Though, you also have to time (no pun intended) the ability so you can stall till the combo start.
Silurian Dragon can be summoned for 12
. Which can be obtained via SNs. The rest of the
coming from the towers can be used as drawing accelerator.
Don't use SNs if you don't need it. You may want to intentionally clog your hand with just enough of them so you can discard that extra hourglass you're not going to use anyway.
There are 4 FGs that doesn't have CC in any way: Ferox, Divine Glory, Miracle, and Serket. Start the combo ASAP against them. You can create an extra dragon or two to compensate if you got a late SoR.
