Currently these are the Level 6 DARK Machine-type monsters that you can opt to Special summon with Psychic Shockwave. But take note, B.E.S Big core’s effect cannot be activated as it was not Normal summoned, and Trifortressops was not Special summoned properly, therefore its immunity to card effects will not be activated.
The description of this card’s misleading. It doesn’t specify that it can’t be activated during battle phase. Tried it out against a Hand thief deck and it didn’t activate during the response of Rising energy.
Sorry but you are wrong, by your logic traps like call of the haunted or mirror force can't be used during the battle phase either. As long as a trap meets the summon criteria it doesn't matter if it's speed 2 or speed 3 it can be used during the battle phase. As it's not working in duel links for this trap it's either bugged or not implemented correctly.
There are restrictions on what can be used in the Damage Step. Does Psychic Shockwave alter ATK/DEF? No. Is it a Counter Trap? No. Is it a Quick Effect Monster? No. Does it say it can be used in the Damage Step? No. Thus, it cannot be used in the Damage Step.
The npc used mirror wall while I had psychic shockwave face down for more than one turn and I had 2 spell cards in hand at the time. For some odd reason psychic shockwave didn't activate. Someone please explain why it didn't activate?
