Fusion Transpiration (Anime)

[mshends]

Normal Trap

When an opponent's Fusion Monster declares an attack: Return that Fusion Monster to the Extra Deck, and if you do, end the Battle Phase, then, if all the Fusion Materials that were used for its Fusion Summon are in the Graveyard, Special Summon all of them to your opponent's side fo the field, then inflict damage to your opponent equal to the ATK of the Fusion Material with the highest ATK (your choice, if tied).

So it's a better version of De-Fusion. This would be a great card against Fusion dimension.

So it's a better version of De-Fusion.

 

De-Fusion can be activated whenever, and you can use it on your own Fusion for an OTK or whatever. Additionally, it's a Quick-Play. 

 

This can only be activated when the Fusion Monster attacks, and only on your opponent's Fusions, and it's a Trap.

 

 

This would be a great card against Fusion dimension.

 

Ironically, it's the Obelisk Force from the Fusion Dimension that uses this, which makes sense, since it'd be silly to not have countermeasures against the Summon mechanic you've aligned yourself with.

This looks silly, but that's about it.

"Ends the Battle Phase" is the only thing this has going for it. It irks me that this isn't straight-up outclassed by Dimensional Prison (since this does damage) or Magic Cylinder (since it sort-of-removes the monster). It's still narrow beyond utility.
