Look, I may be a Jack Atlas fanatic, but even I think the restrictions are stupid
Extra Deck locked to Dragon synchros only? Can't even activate effect of monster? Why would you ever bother? Red Gardna? Mediocre at best.
Won't be surprised if this has actually no usage.
Sure it is. But if you can't use it's effects on that turn or the next, what is the point?
If it's only there to be discarded, I think you have a deck that can handle using a better skill for a better situation.
Wandering King Wildwind can be special summoned if you control a Fiend-Type Tuner with 1500 or less ATK (preferably a Resonator). It's a special summon condition, not an activated effect.
Use it to synchro summon.
Next turn you can banish it from GY to get another Resonator.
Have you tested that? Because it still looks like it's using its effect to summon itself, so unless the wording is weird, I don't think that would work.
I wrote my above comments before even getting the skill.
But yes, I have made a deck and it works exactly as I said.
It's as if Demon's Resonance is specifically made for Wandering King Wildwind.
It is pretty easy to understand. "Special Summon" and "Activate Effect" have different icons.
There are monsters that can special summon itself by activating its effects, and there are others that can special summon itself with certain conditions (Wandering King Wildwind is one of them).
Here is an example deck (might struggle in higher ranks, but fun to play):
Wandering King Wildwind x3
Red Sprinter x1
Red Resonator x1
Red Warg x2
Red Gardna x2
Force Resonator x3
Forbidden Lance x2
Econ x1
Resonant Destruction x3
King's Consonance x1
TTH x1
Extra:
Infernity Doom Dragon
RDA x2
Red Rising Dragon x2
Hot RDA Bane x2
This comment doesn't age well considering King Wildwind + this skill became one of the most consistent searcher + synchro engine you will ever dream of.
So it became tiered in the end.
If we look at how they treat OTK decks, they will limit something to 2 to restrict both trunade and Treacherous, and then releasing new OTK decks the following week that still be able to use both of those card.
The deck itself has several key features that often be missed by other OTK deck, such as:
1. Easy recovery
2. High LP that made OTK from opponent 2nd turn failed
3. 3500 atk beater
4. Combo rarely required a single normal summon
5. Terrifying consistency
