Lately Junk Blade decks have seen an increase in play/finally being recognized as a cancer to the game.
So, Im sure your all wondering how to beat it.
1: Main Board Prohibition.
Of course, the only person out there who bothers to do most of the time is me, but calling Magical Explosion means a dead deck.
Obviously, you cant play it on turn 1, so...
2: Herald of Orange Light
Negating Junk Collector's effect (assuming just one or two will cut it), might save you.
Which means that against FTK decks, gives you game.
Of course, the only reasonable way to run both cards in the same deck, and still have a win condition which compliments these cards would have to be a backrow heavy deck with some Fairies to mess around with in the first place, and already pack some nice meta cards to this FTK.
Hmm. I wonder where I could find something like that.
