Waboku

[Zeppeli Gyro Supreme]

 

I mostly want to know the reason that people run Threatening Roar over this for certain decks. I can think of only a few reasons, such as Zenmaines stll ramming a monster or Tiras getting her pop, but other than that and not revealing a set monster, I don't get it. Are these reasons enough? Waboku has even more chainability than Roar, and can potentially save you from battle phase shenanigans, as well as be used on your turn if you really needed to do your own Tiras (though Zenmaines wouldn't work).

I think the reason is that they still get to attack, which is bad when considering the likes of Glads.

this also stops tricky stuff that activates on attack even if it doesnt deal damage, spirit reaper being the most notable example currently.

Why should allow you to attack at all? 

[Wildflame]

Waboku is cooler if you want to get your Flip Effects (Jar, Worm Linx), or if you want the attack actually happening (Glads).

Here's a card that loves Waboku and hides behind it to troll.

 

OT:

Threatening covers for some of Waboku's flaws (stated above) while the only real downside it has is that you need to activate it before even the first attack is declared, but that's not too hard.

 

I personally like Waboku more because it can combo with other cards unlike Threatening's only function, even if it means having bigger holes for your opponent to slip through.

I don't see why in Prophecies you wouldn't use Waboku over Roar, for two reasons: Tragoedia (situationally) and a set Spellbook Magician (less situational). People still do it, though.

Tragoedia (situationally) 

 

But you don't take damage...

My friend who only plays casual has an old edition of this card and another friend who is also casual thinks that since it doesn't have the "destroyed by battle" part included in the text itself it does a different thing.  It's quite annoying.

But you don't take damage...

Which is why I said situationally. You activate it AFTER you drop Trag to save it and possibly overpower something on your following turn/take control of something without taking a ton of damage.
