Commander ninjutsu allows you to cheat her out for two mana by swapping out an unblocked attacker in play, thus dodging commander tax and enabling her obscene triggered ability in one fell swoop
You need to respond to Electroduplicate with Dualcaster Mage in order for this to work
Its a Blue Sorcery that reads, Each opponent exiles cards from the top of their library until that player has exiled cards with total mana value 20 or more. Its only not as good in Commander because people tend to have higher mana curves, but itll still make everyone other than you sad
How much are bulk Pokmon cards worth
Anyways, I think those decks deserved another win condition, if only to put us out of our collective misery
This is mostly to avoid the look of impropriety, as being able to see the back of the card means theres the possibility of marking (i.e., putting marks on certain cards so you can tell when they pop up in your deck without drawing/scrying them)
