Im a dt player and i have every card you would use in a deck from sakrohm montana and uppers except for guru cr and lyse teria cr so which combination is better sakrohm and uppers montana and uppers montana and sakrohm
Generally sakrohm is not the ideal choise for DT, their cards are great, but many of them will drag out play and make your oponent slower to react, due to abilities such as DR or +life. In short sakrohm forces calculation, which in dt is bad.
So the bestcombination is probably uppers and montana.
Montana have low damage so i think it will be good to combine them with Sakhrom that have many Damager Card (or Life Gainer to make a gap ), good for T1
Uppers + Sakhrom i think will be more stable in T2
