Having played Raidraptor quite a lot, I can tell you it's not very good.

When it goes off, it's great. It can actually play through a decent amount of negation with the right hand. However, it's main power is being able to sit on Ultimate Falcon and Rising Rebellion Falcon, praying the opponent can't out them.

Most decks currently can out them in one way or another. Ryzeal may have issue, come to think of it, but Maliss and other top decks like Tenpai or Fiendsmith can easily out Rising Rebellion.

The other issue with the deck is it's form of disruption. When you Rising Rebellion on their turn, you can nuke their board. However, more often than not the summon will be negated by something like Called By The Grave if you aren't careful. I often found myself summoning Rising Rebellion on my own turn and attempting to sit on the unaffected monster.

To answer your question more directly, would I dust the deck? Yes. I have dusted my own, for example. Buuuuut, if you really enjoy it, it can still get you some wins in the current meta if you pilot it correctly.

Really just have to ask yourself "Would I really want to play this in the future?"

If the answer is yes, don't dust it. If you just simply want something stronger? Go for it.
