"Junk Synchron" + 1 or more non-Tuner monsters When this card is Synchro Summoned: You can target cards on the field, up to the number of non-Tuner monsters used for the Synchro Summon of this card; destroy those targets.
Can only destroy up to 2 cards because Duel Links only has 3 monster zones.
Costly to summon.
In a pure Warrior deck you can use the Immortal Bushi which revives himself every turn if you control no monsters and all monsters in your graveyard are Warrior-types. Then Normal summon.
Junk Synchron and revive a level-2 monster with his effect. Use all three of them to Synchro summon Junk Destroyer and be able to destroy 2 cards. For a quicker summon you can just use The Tricky and Junk Synchron together.
Problem is Junk Anchor comes in the Synchro structure deck with 1 copy. Beyond that you have to pay to get anymore copies. Either choice you make you'll be paying out a lot in gems or cash just to get viable cards to summon Destroyer.
The point is there's options. It's no different to any other card that requires other cards. The fact there even IS a skill that gives you free Junk Synchrons gives it a major advantage over a card like Vampire Genesis or VWXYZ-Dragon Catapult Cannon.
Cool, they finally release Destroyer. Now we need Archer and Gardna to make a full Junk deck.
Too bad Junk is pretty much... junk without Tuning, Quickdraw and Quilbolt.
I think Speeder is a bit too powerful now, since you can pretty much synchro summon into anything with with only 2 cards.
>Akiza dark verger skill
>Special summon junk forward by it's effect (lv3)
>Normal summon junk synchron and special summon dark verger
>Now you can special summon junk destroyer and destroy 2 cards on your opponent.
Now "i don't have 3 junk forward and i wont buy another structure deck"
Gilasaurus and spell striker can be good substitute because both are lv3.
Destroyer does compensate you for using more than 2 monsters, so something like Junk Forward + Junk Synchron works.
This card only generate advantage (+1), if you use junk synchron to summon a level 2 or 1 and you have a level 3 or 4 in the field, but this is very specific or if you summon this using Junk Speeder (this card dont exist in duel links). Maybe Junk Speeder come in the next pack, but Konami sucks 5ds era. And the most synchro decks need 8-10 cards in the extra deck to become playable.
