Notes & Combos
Mostly the same deck and gameplan as my previous one, I removed a Rod as 2 are just fine for what you need.
Dark Magic Expanded can still be helpful to deal with all the non targeted destruction/bounces that cavalry cannot counter, but you can try removing it and something else to make it 20 cards and should still work quite fine.
I won't suggest to remove DMG even if it's a brick because of TDM floating effect.
Most of the star seraph players hit KOG during the first week of august so I don't have many replays against them, general tips is to try to interrupt Scepter and leave the Chair on the field as it is not able to XYZ for less than 3 materials.
