destroy all function

is there a way for those of us who may let their items/towers build up to swipe down to combine all the what ever's we built up? or have a button to do it so there aren't accidental removals of everything.

Do you want to destroy all towers currently built? Or you mean transmuting all cards of a given deck? Or all equal cards (e.g. all Pocket Thiefs)? On the last one we're currently working for the next version :-)

transmuting all cards in deck, not placed. like if i had 50 pocket thief's transmuite them all, or 50 short swords and so on

Alright, thanks for clarifying! This is exactly what we're going to add :-)
