This Level 5 Synchro prevents your opponent from activating cards or effects until the end of Damage Step when it attacks or is attacked. If you activate Enemy Controller or Paleozoic Canadia after Armades has declared an attack, your opponent will not be able to respond to them.
-Use him and Junk Synchron to Synchro Summon Junk Warrior
-When Junk SHyncron is SHyncor SUmmoned chain a card like Birthright & resurrect AtlanteaN Pickeman
-Junk Warrior's effect applies & now he has over 3300 ATK
As a thought, what about using Synchron Explorer in this deck, instead of Junk Forward? Through the use of Level Tuning/Level Augmentation, one could possibly get out consistent Synchros across various levels, with Junk and Explorer being able to constantly bring each other back.
An alternative Junk Synchro recipe uses the Armed Dragon engine to consistently summon Junk Destroyer using 3 cards to max out it's popping effect:
3 x Junk Synchron
3 x Ojamatch
3 x Ojama Blue (Lv2)
1 x Ojama Yellow (Lv2)
2 x Armed Dragon Lv3
3 x Desynchro
3 x Cosmic Cyclone
2 x TTH
Extra: Junk Destroyer + Armades
Skill: KC Bling (if you have a glossy Junk Synchron or Ojamatch), or just run Draw Sense: Dark to guarantee a Junk Synchron.
Clear backrow with CC. Play Ojamatch to discard an Ojama and normal summon Armed Dragon Lv3. Summon Junk Synchron, special summon Ojama from grave, synchro to Junk Destroyer, pop 2 cards, play Desynchro to repeat summon Junk Destroyer if you need to pop more cards. Swing. The opponent will be 2+ cards down so you'll have a huge advantage. If you have Desynchro, you can repeat the summon on consecutive turns to wipe their board again.
TTH helps if you brick and need to stall. Set Ojama Blue to search Ojamatch and set up for Junk Synchron. Run GC if you don't have CC.
