Unexpected Attack

[Thomas★Zero]

 

So this card generally can let you flip a Monster face-up to destroy an opponents card but with a Flip based deck like Krawler and Tindangle this can also inflict some additional effect damage as well as triggering the flip effects of those monsters.

This also seems like a good addition to Subterrors since they have high ATK for the burn.

 

It also works well as a reversal when your opponent is trying to flip your monster face-down to stop an effect or attempt to destroy it by battle (Book of Moon or Maestroke for example), then you surprise them by making your monster apply its effects again (for Continuous effects) or can reuse their effect (for Quick Effects that aren't HOPT), or let your opponent's monster ram into your monster in battle.

 

Also slight nitpick, pointer that Yugioh uses "Defense" spelling instead of "Defence"

 

Overall nice card :)

Try to elaborate a bit more on this (as you are slightly under the word requirement for this section). Pointing out examples or expanding on possible uses will be sufficient enough.

I edited my comment to include more possible uses and a little pointer. Thank you for notifying me!
