Notes & Combos
Back jack is literally just filler, you can use it if you want but, i have to say its literally better to put anything else.
If you know how to use myutants you'll know how to use this. The usual board is 1 Beast, Harbinger and myutant cry with some level 8 myutants in Banish/GY.
Another good board is literally just mist because of all the dark magician decks running around. Play to your hearts content
