I also say currently armor is the Best and safest Strat for some mages, but i feel Most dont know how to Deal with it. The First thing why Do almost all people Run acid Ball? is IT a nice card? Yes
A must have card? No!!!!
There are plenty of ways to remove corrodes. Maybe take dissolves instand of the acid Balls
And dissolve the right thing and Not always which is just Best for the next turn. High Tank with enough spare equipment Lacks killing Power or dispels against dot. So use that.
And never forget Piercing, a critical strike Dark pact slayer just ignores leather Boots vet Belt Chitin armor and rhino hide at once.
Chitin armor wont Change that, and I probably still run a dragonsacle in case, except if i'm a Natur mage
Back to the cards, both cool but for me they could have better surviveability
