Select 1 face-up monster your opponent controls. If you Synchro Summon this turn, you can use the selected monster as a Synchro Material Monster. You cannot conduct your Battle Phase during the turn you activate this card.
Use Synchro Material so that you can use one of your opponent’s monster for Junk Destroyer’s summoning. This lets you remove a monster from your opponent’s field, and also makes the max number of non-Tuner monsters you can use to summon Junk Warrior 3 for more destruction.
I'm supposed to Set this, wait for my next turn, Summon a Tuner and then target a monster my opponent controls to Synchro Summon with. Afterall of this I still have to skip my Battle Phase? Really? Also you will have to run a Level 1 Tuner if you want to use a Blue-Eyes or a Masked HERO Anki since the highest Level generic Synchro we have is a Level 9 (Giganticastle).
