It's entirely different, for one control warrior had way too much good removal, high tempo cards like weapons to not fall behind on tempo etc. In shadowverse you dont have weapons to counter the low tempo play of gaining. Aggro and midrange are fast decks and gaining armor wont always be possible because you sacrifice tempo to do something. And azazel is not the same as armor. azazel hard caps damage at 3, hit him for 20 damage? he only takes 3 damage. armor is different than that as it's essentially bonus health.

it wouldnt slot down roach much but it would make roach have to use an extra roach to finish maybe more some if you can stack up enough armor. Low tempo plays like gaining armor would be possible against decks like roach or daria rune who do very little boardwise in the early game as they just build up their win con and would give you a bit of buffer to help protect yo
